The 2011 RX has a generation 6 navigation system that has its data stored on a hard drive. It can be updated only by a Lexus dealer with proprietary software ("Navigation Update Tool") through the vehicle USB port from a master DVD that only the dealer can get. If you ask a Lexus dealership parts department, I think you will find that navigation updates for your RX were discontinued some years ago - maybe in 2017 or 2018. If nav updates have been discontinued and if the Lexus dealer has or can obtain the software and master DVD for the final map update, it will be up to you to decide if it's worth spending the money to get maps that won't be current. You should be able to see what map version you currently have by going into your navigation settings. If you're lucky, a previous owner updated the maps at some point. This particular navigation system can be pretty expensive to update. The retail price of the update itself was around $170 and dealers usually charged that much or more for labor. It wasn't unusual for the total cost of an update to exceed $350 which was probably why not many people got their navigation systems updated. I am not certain that the 2011 RX with navigation can read text and email messages. I do remember that the function was added to some vehicles for the 2012 model year. Do you have the navigation manual and is this function described in it? Or can you see the function on the phone screen? If your RX does have the text/email reading and response function, it's pretty easy to set up for an Android phone. Not that you're interested but iPhone iOS didn't fully support this function until recently. I'm providing most of this from memory so you might have to do some reading and investigation for yourself. After you pair your Android phone with your RX, go into your Android phone's Bluetooth settings for your RX and give your RX access to your contacts and messages. It should be a matter of toggling the settings from off to on if they aren't on by default. Then go into your RX navigation system's phone menu and find and enable the reading of text messages and/or emails. If your 2011 RX does not support the reading of text and email messages, all is not lost. There are apps on Google Play for Android phones that can do it. I use the Android app "A2DP Volume" to read text messages to me in one of our vehicles that doesn't have the built-in function but it doesn't allow me to respond with "canned" replies like the Lexus and Toyota systems do. If you want to experience additional "trauma", then install Lexus Enform on your phone from the Google Play store. I originally had great hope for Lexus Enform and its Toyota Entune sibling but both were plagued by stability issues. The operating system was from a subsidiary of Research In Motion (the Blackberry phone company) and we know where Blackberry went. Still, you might find an app or two in Enform that you might appreciate but I'm not sure what apps are left for the original Enform. If you don't have manuals for your RX, you can order hard copies and view them online in the Owners section of the Lexus website. Edit: Whoa! I just saw that you are in Canada - Alberta no less. That means that your 2011 RX may not have Enform and other functions that were on U.S. market vehicles. I do know that, later on, some of the Enform apps weren't available in Canada due to copyright restrictions. Some functions weren't even available on U.S. market vehicles when they were driven in Canada since the restrictions were based on IP address.

As I mentioned in a previous post in this thread. Toyota/Lexus navigation systems have never had an option to mute radios when navigation instructions are broadcast. It's been that way since the 1990's - at least in the U.S. market. Where are you located? Something that might help you is pressing the MAP button to have audible navigation instructions repeated when you don't hear them. I do that quite often. By the way, can you see the navigation instructions in your HUD?

A more typical "plus zero" alternative would be 235/50-17 which would be a -0.22% diameter change. That, however, might make your car feel and be more sluggish. Why are you considering 225/55-17 tires? I could see doing that if the OEM size wasn't available and the current tires were shot.

That is odd. But the part number that Lexus sells for the 2020, 2021 and 2022 RX450h is the same which would seem to indicate that a Curt hitch for a 2020 would likely fit a 2021 and 2022: 2020: https://parts.lexus.com/p/Lexus_2020_RX-450h/Tow-Hitch-Receiver/69522951/PT22848160.html 2021: https://parts.lexus.com/p/Lexus_2021_RX-450h/Tow-Hitch-Receiver/69522951/PT22848160.html 2022: https://parts.lexus.com/p/Lexus_2022_RX-450h/Tow-Hitch-Receiver/69522951/PT22848160.html

The Lexus, U-Haul and other brand hitches for the RX are all of the "receiver" type. The "ball mount" you are referring to is bolted to a drawbar which inserts into the receiver. Bike racks for receiver hitches similarly plug into hitch receivers. Lighter capacity receiver type hitches come in two formats - 1 1/4 inch and 2-inch. A 2-inch receiver hitch is vastly preferable over the 1 1/4 inch receiver hitch if it's going to be used for accessories such as a bike rack or cargo tray. The Lexus website says that the receiver hitch Lexus sells for the 2022 RX450h is a 2-inch receiver hitch: https://parts.lexus.com/p/Lexus_2022_RX-450h/Tow-Hitch-Receiver/69522951/PT22848160.html Don't even think about getting a 1 1/4 inch receiver hitch if you are going to carry two e-bikes. E-bikes can be quite heavy. There's no way I would put even one e-bike on the Pro-Series 2-bike rack that plugs into the 1 1/4 inch Curt receiver hitch that I installed on my wife's Prius v - it would be too unstable. I would, however, be comfortable with carrying one or two e-bikes on the far more robust Pro-Series 4-bike rack that plugs into the 2-inch receiver on our Sienna. Maybe a bike shop that sells e-bikes can help you identify a bike rack that works particularly well for carrying two e-bikes. LOL, my wife is after me to help her find an e-bike that fits her. We've bought so many bikes for her and none have worked to her satisfaction including her current quite expensive Trek "hybrid" (mountain bike type frame with road bike type wheels). It's difficult to find a bike that's easy to mount and dismount for a 4' 11" tall woman with limited mobility. Finding an e-bike that small sounds like finding a unicorn. If you want to see what a drawbar with a ball mount looks like, here is a photo of the "kit" I bought that includes the draw bar that plugs into a 2-inch receiver. This particular kit includes easily interchangeable balls of the most common sizes. Not that it's useful, here's another photo showing our Pro-Series 2-bike rack that plugs into a 1 1/4 inch receiver and our Pro-Series 4-bike rack that plugs into a 2 inch receiver. I suspect that a platform type bike rack would work better for e-bikes. .

The RX450h is suitable for towing although to exploit its towing capabilities it should have the factory installed tow prep package that I mentioned in my first post in this thread. The components of the tow prep package have nothing to do with the hybrid traction motor or a "rear diff".

I looked at the Uhaul hitch on their website. It actually doesn't look bad which is saying something since some of the most butt-ugly hitches I've seen have been from Uhaul. The installation instructions say that trimming an "appearance panel" in two places is necessary. Are you OK with that? I've occasionally used Uhaul services and have found that the skill levels of their employees are EXTREMELY variable and I do mean E-X-T-R-E-M-E-L-Y !!! If you go with Uhaul, I suggest that you carefully interview the person who is going to do the installation to see if he is at least conscious. Installation looks very easy and similar to my installation of a Curt hitch on our Toyota Sienna which is a close cousin of the Lexus RX and shares many components. If you are handy and have the appropriate tools including a torque wrench, you could do it yourself. Installing a hitch on your RX looks easier than on our Sienna which took only about an hour including the time it took to trim the underbody plastic panel. It would likely require elevating the rear of the RX such as with jack stands.

You are using the correct terminology - at least the same as used on the Lexus website. The optional towing preparation package includes engine and transmission oil coolers and a "heavy duty" radiator and cooling fan. It used to include additional wiring in the back for attaching trailer light wiring but it's not listed as one of the features. None of the engine compartment components are needed for installing a receiver hitch for carrying a bike rack or for towing light trailers such as a small utility trailer. I've long been perturbed that the towing prep package isn't standard on the RX since it is inexpensive and was made standard on its Toyota brand siblings in 2014. Toyota offers kits on some models to relocate the kick sensor when installing a receiver hitch. Even when a relocation kit is not available it has been found that it sometimes possible to relocate the kick sensor to make it work after installing a receiver hitch. Installing a receiver hitch will not void the warranty. The impact on a lease is a different matter since installing a hitch sometimes requires cutting plastic body panels. If you are going to use a receiver hitch only to carry a bike rack, then you wouldn't need to install trailer light wiring or buy a draw bar or ball. For example, I installed a Curt receiver hitch on my wife's Prius v wagon only for carrying a 2-bike rack but I didn't install or buy anything else. Oddly, I don't see a receiver hitch for the 2022 RX450h listed on the Curt website: https://www.curtmfg.com/ I wonder what's up with that. The last three receiver hitches I've bought have been the Curt brand and they've all cost a fraction of the price of an OEM hitch. You should still be able to buy a Lexus brand receiver hitch but you might lose the functionality of the kick sensor if it can't be relocated to work properly.

The Platinum badges may be impossible to remove and reuse since they seem to get damaged when they are removed. In around 2010 I watched a body shop employee remove and install several of them trying to get one lined up correctly on the 2000 LS400 I drove for many years. The replacement badges were like peal-off stickers and somewhat different from the originals which were sort of set into a rubber or plastic underlay. I suggest leaving the badges off. You might be able to get new badges made by a jeweler that makes custom pieces but I suspect the cost would be very high - hundreds of dollars. Who needs badges anyway? I've sometimes removed exterior badges.

It sounds like the OP has only a valet key which cannot be used to unlock the trunk at the keyhole by the taillight. The OP needs to get a master key which can be fairly expensive. I think a master key can be obtained without replacing an expensive ECU as long as the owner has a valet key that can operate the ignition and allow the car to be driven. The master key will have a button that can remotely lock and unlock the vehicle. Unlike the master keys/fobs for second generation LS400, the master key for the first generation (90-94) has only one button. While getting a master key may be fairly expensive - up to several hundred dollars - it's critical to have at least one. If you have only one valet key and lose it, you are SOL and may have to spend far more. I was so protective of the master keys for the 1990 and 2000 LS400's I owned that I had extra ones that I kept in a fireproof safe.

The setting I'm referring to is in the vehicle. Access it through your in-dash screen. Your navigation entertainment manual shows how.

The first thing I'd try is to go into Settings and verify that "Bluetooth Power" is set to "On".

I would suspect a broken wire at the hinge. Unwrap the wires at the hinge and look for wires that are cracked. You might have to wiggle the wires to determine if/where the metal wire cores are broken under the insulation on each wire. I had to splice in short lengths of wire on my first LS400 when the car was 13 years old due to the wires at the hinge breaking. The friend who bought the car from me had to do again as the car aged.

At least you're making progress. Not that it will help but here an audio system diagram from Auto Repair Source that is supposedly for a 1995 SC300 although it doesn't indicate if it's for the standard or Nakamichi system.

The water is most likely getting in between the trunk lid and the gasket as it did on the 1990 and 2000 LS400's I drove for a total of 24 years. I suppose you could replace the gaskets if you can find new OEM gaskets although new gaskets sitting on shelves for 25 to 30 years might not be in great shape. Or you could look for similar aftermarket gasket sold by the foot. I never replaced the trunk gaskets on my cars but I tried to get more proactive about removing the water with towels. I also frequently cleaned and lubricated the trunk and door gaskets with spray silicon but I don't know if it helped that much. There's not much that can be done to improve trunk and door gaskets after the become compressed and collapsed. Water in the trunk and other places also contributes to high humidity which can cause corrosion in and failure of electrical components. Maybe the solution is moving to Arizona! Edit: One more thing. Per my previous post in this thread, does your SC300 have or is there evidence that it had a dealer installed Lexus brand cell phone? Failure of the phone ECU in the trunk can put the audio system in permanent mute mode although the audio can sometimes still be heard at a very low volume. If it has a phone ECU in the trunk, remove it and check the pins in the ECU connectors for corrosion. Even if it does not have a phone, check the connectors in the trunk for a phone and ensure that there is no corrosion on the pin in the connectors. All Lexus SC of the 1990's were prewired for dealer installed phones. The phone ECU connectors have a mute pin. If this mute pin gets grounded by corrosion, the audio system will go into mute mode. I've had substantial experience with this situation on Lexus cars of the 1990's.

Based on the owners and navigation manuals, it appears that the SC430 first got Bluetooth for handsfree phone for the 2006 model year but didn't get A2DP Bluetooth for audio streaming until it's final (2010) model year. Several companies offered Bluetooth A2DP and aux-in interfaces but I don't know if they are still available. The SC430 infotainment system was pretty much left to rot in it's final model years - probably due to low sales.

There probably aren't many recent threads about this problem since there aren't very many SC300/SC400 still on the road but there were a number of threads "back in the day" about the SC amps getting damaged by water. You could look for a good used on on eBay or maybe you can find a company that repairs them. Do whatever you can to keep water away from the amp. Trunk mounted Lexus telephone ECU's suffered a similar fate and often put the audio system in permanent mute. If your SC400 has a phone ECU in the trunk, disconnecting it might solve your problem.

I don't have a UX but on most Toyota/Lexus vehicles, there is a "Connect Phone" button displayed on the in-dash screen after you press the off-hook button on the steering wheel. Could one of the iPhones displayed on the in-dash screen be a phone that's no longer used? If in doubt, delete and re-add the phones. You should be able to rename the phone in the car's Bluetooth settings. And if you want to, you should be able to rename the vehicle in the phone's Bluetooth settings.

The problem you are having has occurred on every vehicle we've had that had Bluetooth. I'm sure your wife can learn to connect her phone if it's not connected. My wife may be the most technically challenged person on earth and she's learned to do it. An easy way to verify which phone is connected is to press the off-hook button on the steering wheel and look at the screen to see which phone is connected. If the desired phone isn't connected, then press the virtual connect button and then select it from list on the screen. If the desired phone still doesn't connect, first try toggling Bluetooth on the desired phone off and then on. In rare cases, it's been necessary to reboot the phone or turn the vehicle ignition off and restart the engine. I used to have the problem far more when I had my home phone system automatically connect to my cell phone as I entered our house. Our home phone system tended to not "turn loose" of my phone when I went to the garage and started one of our vehicles. Most of the time I would have to manually sever the connection with the home phone system and manually connect my phone to the Bluetooth system in the vehicle I was about to drive. The problem went away when I stopped connecting my cell phone to our home phone system. I realized that I'd rather have my cell phone in my pocket when I'm home and I my current cell phone's long battery life means I don't need to charge it as often.. BTW, the latest Toyota/Lexus in-dash systems, such as the one on the Lexus NX450h my wife is getting, allow two cell phones to be connected simultaneously. I'm not sure that is an improvement but we'll see how it goes.

You may have the dreaded disease known as TPS - Tight Pants Syndrome. Something in your pants pocket may have pushed against the unlock button to cause the windows to roll down and then against the lock button to lock the doors. I've occasionally had this problem although I've become careful to remove keys and fobs from my pocket when I'm home. You're fortunate that it happened in your garage. It's happened to some when their vehicles were parked outside in the rain. At some point, Lexus vehicles began to come from the factory with this feature set to OFF by default - maybe due to the prevalence of TPS. Unfortunately, only a Lexus dealer can change the setting on the ES350 of generation you have. This and other customizable settings are documented in the Customization section of your owners manual.

If the adaptive distance sensing feature of your cruise control no longer works, the dealer must have deactivated it with Techstream or via an in-dash setting that you can control yourself. Laser based adaptive cruise control was available in all years of the LS430 in the Custom Luxury and Ultra Luxury packages.? Its laser sensor was in the lower grill on the passenger side. The LS430 got radar based adaptive cruise control and automatic emergency braking for the 2004 model year as an option on top of the Custom Luxury and Ultra Luxury packages. It's radar sensor was behind the "L" emblem in the front grill like it is on your LS500. Radar based adaptive cruise control is one of my favorite features. All our current vehicles have it. I won't even rent a vehicle without it. Even a fully autonomous driving vehicle requires oversight from the driver. One can't just "zone out" while the vehicle is driving itself. Some who have done that have made the news by crashing. I'm rather looking forward to full self driving vehicles. A 700 mile medical related trip last week sure would have been less tiring with that. I would have bought a Tesla with the full autonomous driving option by now if there were enough convenient charging opportunities where we drive or if they had substantially longer range on a charge..

I would expect the actual speed to be slightly less than the speed shown on the speedometer. The difference is usually between one and three mph. After setting the cruise control speed you can adjust the cruise control speed with the steering wheel controls to get it to exactly where you want it. Do you not like the Dynamic Radar Cruise Control? All vehicles manufactured by Toyota since around 2018 have it. It takes some getting used to and even some skill to use efficiently. I've often driven 200 miles or more while using radar cruise control without ever touching the gas or brake pedals.

Sat nav was an extra cost option on the RX300 and RX400h in the U.S. market. Some people bought it. Other people didn't.

Sorry, I didn't understand exactly what you wanted. It is common for forum software to be configured to turn on "follow" by default whenever you post. If you don't want to follow a thread after you post, then immediately turn off following after posting. I assume that this is a forum software configuration setting that could be changed by a forum administrator but many people prefer to automatically follow a thread after posting.
