The map in you car is probably way out of date! Its probably Version 2.1 or even 1.0! My Version 8.1 has the address listed as 2185 Salem Rd SE, Conyers, GA. Pick up the new DVD (Version 10.1) at your local Lexus dealership. Part number PT219-GEN23-10... won't be available until October 1st.

The new DVD updates are coming in October for V10.1. For an 05MY GX470 you will need part number PT219-GEN04-10. Pick it up from your local Lexus dealership for $199. Note - You will have to either eject the old map disc to see the version number (probably V4.1) or check via the touch screen.

The TX+ color is PINK and TX- is YELLOW. With that info you must use a multi-meter (or ohm meter) to see if the resistor inside the AM/FM RADIO reads 75 ohms of resistance. If the factory radio does not read 75 ohms of resistance NOTHING will work properly.

Depending upon the sound system (Mark Levinson for example) will have a dedicated channel for each loud speaker. If this is the case (as is for navigation equipped vehicles) then each speaker has its own dedicated channel. However, for base audio systems without any premium audio (standard AM/FM/CD in the dash) you simply wire up your crossover with the 'in' from the factory wires, and out of the Infinity crossover to the respective speaker (mid-bass and tweeter). Lastly, the audio output of the headunit for all older Lexus and Toyota vehicles is left+ left- and right+ right-. Thus if you take out your amplifier (if equipped) you will lose the ability to fade front to rear. The AVC-LAN instructs how to distribute the sound front to rear via the TX+ and TX- (communication) wires. New Lexus vehicles like the 2010 RX350 have changed to a MOST network which will make changes (besides loudspeakers) nearly impossible.

Just 1 note..... any music coming from a compressed audio source (MP3 or satellite radio) will sound bad in comparison to CD playback. CD and FM should sound good in comparison to satellite radio. They may say 'digital quality' but it is compressed none the less.

The factory radio has a 75 ohm resistor in it... its considered the 'master component' in the system... not the amplifier. Without this 75 ohm resistor in the network nothing will work normally. Navguy, Please explain, I am interested in your response. If you get an electronic wiring diagram (EWD) you will find two wires that go into the radio (along with other componenets) that are labeled TX+ and TX-. When you removed the radio (master) you took the 75 ohm resistor out of the network. So if you install a 75 ohm resistor (across the TX+ and TX-) in the appropriate pins the rest of the stuff should work.

The cost would be prohibitive since it involves a different amplifier, cables, touch screen, etc.

Pick up a brand new version V9.1 from any Toyota (86271-GEN04-09) or Lexus (PT219-GEN04-09) dealer for $199; reduced from $265. Then you don't have to worry if the crap on ebay is legit. Your navigation computer is in the trunk.. I think on the right side. It's a little hard to get to it so read the owners manual carefully and be sure to eject the old disc first!

Contact Fujitsu Ten in California, provide part number and ask them if they will repair for you. If they can (or will) you will not be able to drive your car in the meantime.

Almost impossible since the vehicle harness (without navigation) is missing so many inputs/outputs/parts: Speed Pulse Microphone Parking Break Different amplifier GPS antenna Navigation computer Navigation monitor Steering wheel controls for voice Go aftermarket... much easier.

The new DVD V9.1 is available for $199. The only items updated is the mapping information (roads, streets, business info, etc.). You wont find any changes to the operating system. The new disc, in comparison to your V3.1, is quite different. Thats over 6 years of changes! Lastly, the installation is easy. It will only take 2 minutes to update after you install the new disc. The navigation computer is in the back near the spare tire. Simply slide the cover over the button and press for 2 seconds. The old disc will eject automatically. DO NOT insert the new disc first or you will damage it. As far as the stereo is concerned you will be spending a ton to replace the radio, monitor, amplifier etc. Your climate control goes through the monitor in the dash too. I would suggest that you only replace the speakers, or amp and speakers.

If you phone supports the phone book access profile (PBAP ) you dont have to record a voice tag like the old GEN5 system. To use the system say the name as you have programmed it into your phone.

The wrong DVD map disc has been installed. Lucky for you the price just dropped to $199 from $265. Get Lexus part number PT21-GEN05-09. The part number on the DVD map disc must be 86271-5302X(the X is a placeholder)... so if the disc in the navigation ECU doesn't match then its just a wrong map disc.

The new DVD map disc are available for $199 from Lexus or Toyota dealers. You either need 86271-GEN23-09 (Toyota) or PT219-GEN23-09 for Lexus. Both will be available on October 1st. If you do buy anything of eBay the part number on the DVD map disc must be 86271-3303X. The higher the last digit (X) the newer the disc. The new map disc part number will be 86271-33038.

I also have a 2002 SC430 that is badly in need of a nav update - - but I get mixed reports about the 02 year and updates -- most state that LEXUS PT219-GEN23-08 is the update - but some add a warning that it is not recommended for the 2002 ?!!! I sure would like to get a disk at a reasonable price since the dealers charge in excess of $250 - - heck my Garmin NUVI is more modern and more accurate - but I want to use the build in NAV as long as it's in the car. ANY help will be greatly appreciated - PMquickclick@gmail.com = FASTFINGER FYI - I just got an email from my Lexus dealer saying the MSRP is $199 until the end of June for V8.1.

Call Lexus customer care and have them capture the address that is missing. They will report it to the map suppliers... NAVTEQ or TeleAtlas. Or you could report it to NAVTEQ directly. The link is: http://mapreporter.navteq.com/dur-web-exte...amp;language=en Thanks Navguy. I just did submit our address for inclusion in the database. Funny thing is that I thought that's why we spend the big bucks with these mapping companies to continuously monitor road, commercial and residential changes using their staff and resources. Why else would I spend hundred$ of dollar$ for a DVD? I really don't think it should be up to individuals to proactively find the mapping companies and submit information instead the mapping companies should interactively work with city, county, state and federal public records to cull this information from planning, zoning and building permit records to update their databases. Now that would be "earning" their money! Very, very true.

Alright thanks man. Where and what disc should I buy for it? In other words, what is the newest version of software for it? 2004 RX 330 86271-3303X (on the disc - the higher the last digit the higher the version) V8.1 is the most current disc available and was released in November of 2008. You can acquire this GEN23 map disc from a Toyota or Lexus dealership. Dealers are free to set their own pricing so shop around. I'm looking around for GEN23 map disc for 2004 rx330, but everything I'm reading says 2004 rx330 is a Gen 2/3 design and v8.1 wont work with Gen 2/3 system. Is this incorrect? What IS the latest version I can get for Gen 2/3 system for 2004 RX330? thx. Hey, Lexus is offering V8.1 for $199 MSRP! Just got an email from my dealer. The part number you need is PT219-GEN23-08

Go to http://btjunkie.org/ and search for a Toyota or Lexus generation 3, data 7.1 Nav DVD image file copy. (iso format) Download the file with a bit torrent. Then you need image burning software on your PC and a DVD drive that can write to dual layer DVD's. Today, I found a data 6.1 is on that web site. That should be much better than what you now have. A word of caution: Once you successfully upgrade from the oldest data version, the 2002 disk will not longer work because the ROM was upgraded and you will have to use a data generation of probably 3.1 or higher. Originals of those probably can be found on Ebay for around 50 bucks. Still better than what you have now. Be prepared for some difficulty as not all copies will work. The 7.1 data version I downloaded works perfectly in my 02 SC430, but doesn't work in my 01 LS430. I have a data version 5.1 original DVD disk in that car, also generation 3. Data version 7.1 is better than 5.1, but I can live with 5.1. My 03 ls430 was wrecked and I'm getting an 06, so I have a 7.1 dvd for sale. It's on the for sale forum or pm me if interested. Gary K FYI - I just got an email from Lexus offering version 8.1 for an MSRP of $199. Did anyone else get this summer promotion?

Your map disc must be 86271-3304X... the higher the last digit the better. If the new disc you bought is anything but -3304X then it will not work.

Bluetooth stereo or A2DP is available on the 2010 RX and Toyota Venza - soon on the Avalon and Prius too. This will allow you to listen to the music on your phone over the stereo in the vehicle (without cables). Make sure the cellphone is A2DP compatible as well.

I would venture to say that adding the system from another year would be nearly impossible. There are so many factory harnesses that have to be purchased it would be so much cheaper to go aftermarket. Sorry.

Check the Navigation Quick Guide or press the talk switch on the steering wheel and touch or say 'HELP'.
