Is It Possible To Upgrade

Recommended Posts

I am a newbie and just acquired a sweet 2003 GX 470 with NAV, DVD and ML. I am hugely disappointed that it has no input for ipod or MP3 so I have a few questions

Is it possible to include an external input source. There seems to be no clarity about 2003 with nav option in all threads i have read

Is it possible to upgrade the firmware for the screen so it is more modern or change it out completely so i can solve all the problems with a screen with USB, bluetooth and ipod inputs

Any help will be appreciated.

Hi dcfish...thanks for responding. I have seen your threads and responses all over the forum and they have been very helpful. I have contacted Vaistech and received recommendation. I have been offered SL3i or MML. Neither is a bluetooth solution.

Secondly, none of this solve my other problem of improving the look and feel of the screen. Is it possible to swap out the HU (i hope this is correct) for an after market option or for newer models of GX with better look?

While I love Vaistech and their products, you really should contact them by phone to see if they may have developed something that may answer your questions. Otherwise you may be stuck going to some sort of an aftermarket stereo/sound system shop and having them assist you in finding some sort of a solution. Be sure to bring a bucket of money!

How much are you willing to pay to update a 10 year old vehicle? A simple aux-in would allow you to have virtually all the functionality of the latest Toyota Entune and Lexus Enform systems as long as you are willing to control the apps from your phone's screen.


I've noticed that VAIS has been focusing their efforts on newer vehicles with the latest nav systems. I would not expect them to go back and develop anything for older Lexus vehicles.

If you have to have A2DP Bluetooth streaming, you could add a simple aftermarket Bluetooth receiver to an aux-in from VAIS, iSimple, etc. - maybe use a splitter so you can have both a plug-in and a wireless connection. I thought about doing that but I don't mind plugging the aux-in into my phone since I usually get my phone out of my pocket to charge it while I am driving.

I'm not very impressed with controlling applications through a nav screen. I get a lot more apps and features from apps when I control them directly from my phone through an aux-in or Bluetooth in our new Toyota than through Entune on its nav screen. Phone technology is way, way ahead of in-dash nav technology.

Thanks for all the postings. I think I am leaning in the direction of 1990LS400 as it appears there is nott a lot I can do with the 2003 with nav (from my research on forums). Any recommendation on auxillary input options or is there a diy available as I am quite comfortable doing electronic/electrical upgrades.

There is the Parrot Mki9200 or something like that, that can integrate Bluetooth and also has an aux cord and iphone cord too. So not only can you do Bluetooth calls but you can stream music thru Bluetooth also.

Denslexus,

from my reseach, it appears that the Parrot mki2000 is suited to GX 470 without Navigation. Do you know if anyone with navigation has installed it?

According to the following webpage, "Adapter QCJBL-2" is supposed to work on "all incl Mark Levinson": http://www.quickconnectproducts.com/Find/find.php

I have no idea if that is accurate. I had planned to install a Parrot Mki9100 in my 2000 LS400 but decided on a different solution due to the amount of hardwiring that would have been involved due to no adapter harness being available. The Mki9100 has a smaller non-color display.

I suspect aftermarket kits like the Parrot are going to be fading away as more vehicle comes with all this technology standard. Bluetooth technology and aux-in/USB ports are becoming standard on very inexpensive cars.

Update

Hi everyone. my research finally took me to a product from a company called Yatour.

http://www.yatourcarkits.com/older-lexus-usb-sd-aux-mp3-interface-adapter-yatour-p-153.html

They have several options: Usb, SD & Aux input or ipod input. You can also combine bluetooth with any options. Price is very reasonable so i am very excited about this. However, to keep both the adapter and CD changer, i need to know how if it the CD changer that is directly connected to the head unit radio (CD changer port) or the nav system as i have not opened up mine before. I will appreciate any pointer on this.

Final Update on this topic.

I installed the Yatour adapter with Aux and ipod inputs. i also combined bluetooth with the adapter and it works like a charm. anyone considering an adapter should look at this. The entire set up cost about $120 and the installation was free....did it myself.

Thanks everyone for all the help.

Hey Adey, I'm about to pick up an 03 gx with nav and was trying to find the adapter you picked up. The link and website seems to be not available anymore but I found the yatour products on amazon. Was wondering if your adapter looked anything like this one...

YATOUR Car Digital Music Changer USB SD MP3 12pin for TOYOTA and LEXUS series https://www.amazon.com/dp/B007V9W8H6/ref=cm_sw_r_cp_api_4oKyxb6AMSREP

 

The table lists the 03 gx but it doesn't specify nav so I wanted to double check. I tried a tape adapter first and it sounded awful so I'm hoping there is still an alternative to get my phone hooked up! Thanks for anyone that has a more recent way for fixing this...

      2003 ES300 - The passenger side light on the trunk is not lighting and indicator on dash shows it is not working. I found the replacement bulb (7440 single filament) but have no idea of how to remove trunk liner for access to the bulb. Trunk liner seems to be held in place with plastic push pins and I don't want to break any. Any advice will be appreciated.

      What do you all suggest as the best pure synthetic oil for a 2003 ES 300 with 209,000 miles? Runs perfectly with a very small (weekly drip) using Mobil 1 (5W-20). Also, what filter is recommended. Located in NC Piedmont region. Car is only driven <5000 miles a year.

      The low beam HID headlights on my 2003 GS430 stopped working.  So looking into the cost etc, I decided to go with the OEM Philips D2R on Amazon for $44 each and replacing both seemed like the appropriate plan of action to get the best light.  My local autozone et al wanted 70-90 for 1.  There are cheaper alternatives on eBay and Amazon but I wanted to do the job once and maybe again in 13 years.
      There a gray plastic ~5" diameter plastic covers on left and right sides right behind the headlight housing near the bumper.  The plastic covers are removed by twisting them counter-clockwise.  Once you remove the covers you will either see a 9006, non HID light bulb which is an angle connector with bulb built in or a HID D2R which will have a silver colored metal protector and a silver colored sheathed connector wire.  
      The metal connetor protector cover is held in place by two clips; top and bottom of the bulb holder, 12 & 6.  Remove the bottom of the cover first and then slide the metal cover out from the top clip.  The clips are bulit into the bulb holder so you can't lose them and are simple spring metal.  The metal covers will have cutouts to match the clips on the bulb holder/housing.  Once the metal covers are off you can now remove the bulb connector.
      The bulb connectors are horizontal position and need to be rotated 45 degrees or so to be released.  The bulb connectors have 4 positions where the bulb's two round knobs connect into so it's hard to tell if you should rotate CW or CCW and left and right sides rotated differently on my car.  The connector will only rotate one direction and it comes off fairly easily so don't force it.  
      The buld has a round base with round winglets that secure the bulb to the slotted connector.  Once the connector is removed you can remove the bulb.  On my car, the right connector had to be turned 45degrees up to fit on the bulb and then rotated down to be horizontal and the left was attached down and rotated up to be horizontal.  Remember how you took the connectors off as you will have to put them back on.
      The bulb base has indentations on it that match the headlight housing and the bulb can only be inserted one way.  There are two spring loaded clips that hold the base into the housing.  The clips are long spring wires that are fixed at the bottom of the housing and secure around two two metal tabs at the top of the headllight housing.  Pushing the rounded end of the spring in and pushing it from under the metal tabs will release the bulb from the housing.  Observe the shealthed wire connector and its location relative to the springs, as you will need to replicated this during installation.  Be careful removing the bulb as the external wire is exposed and you can break it very easily.
      Reversing the procedure will be a lot easier now that you've gone through the removal process.  The bulb external filament will be on the bottom and the indent in the bulb base located opposite at the top which is important to remember when installing it.  Once you have identified the indent on the headlight housing base ^|^ and the corresponding matching indent on the bulb base the bulb will easily slide in place and the metal springs will easily get pushed underneath the metal tabs.   Connect the connectors, rotate to horizontal position.
      The metal backing cover should be slipped under the springs at the top and connected first and then snap the bottom in place.  Keep the connector wire in the same position and then put the gray plastic cover and voila!  it's done and you have succesfully saved yourself hundreds of dollars!  
      My descriptions are pretty exact and I have never replaced HID headlights on any other car so can't tell if my car/year is unique or not.  I would be surprised if there are different methods as "variation is the enemy of quality" (Deming) and Japan used Demings theory in creating their reputation for quality!
      Have fun

      I am looking at a 2003 GX 470 for sale at a local dealership. It has 153k miles and they are asking 11,500 for it. Is that too overpriced? It looks like it is in very good condition. I really want this car as a family car, but that seems overpriced for a 2003 with 150k miles. Any advice is much appreciated. Thanks, Josh.

      I have a clean and well-maintained 2003 GX 470 with 171K. All maintenance performed – no leaks, no issues, etc. Recently, it started making a ticking noise when warm. It also had a slight "knock" to the engine as well. I had the lifters adjusted and the PCV was replaced. It's definitely better but not "Lexus-smooth." The mechanic and dealership say it's characteristic of this engine/year. I've read other threads that mention similar issues but nothing specific unless I can't find the thread.  I've noticed that when I press the gas pedal down while idling there is no knock noise and the engine remains smooth, the ticking seems be less severe as well? Can anyone out there give me some guidance? Thank you!
