  1. Good Evening All - I recently bought a 2003 GX470 which I like much more than the X5 I had prior to it. The only issue with it was that the GPS reception didn't work even though the antenna was plugged in. I found the secret screen and made the big mistake (didn't know at the time) of choosing to load a program like US-XXX in an attempt to fix it. Now, when I turn my car on, I get a screen (1/2 English & 1/2 Japanese) saying"Error; System unable to access the program" followed by "Incorrect Program Disc. Please insert proper disc." I've searched all over this forum and others as well as tried a few fixes - all without any luck. Below is what is happening in more detail as well as what I've tried already to fix the issue. The Issue in Detail When I turn the car on, the display shows the Lexus logo for a couple of seconds, a screen saying "Please wait while the system updates for about 3 seconds (if I have any disc but the original DVD in), then the error message above. The Map, Navigation, and Menu buttons do not work (show the message,) but Display, Audio, and others do work. The car came with an original 3.x (I think) version maps disc. It's a Gen 2/3 unit. I purchased the 10.1 and 13.1 upgrade discs and have copied them to DVD-DL which I am using to keep the expensive retail discs unharmed. Upon purchasing the 10.1 disc, I put it in which updated the system (about 5 minutes) but kept getting disc unreadable messages (even with OEM one) so went back to older maps disc. Just got 13.1 in this week to try to fix this issue but do not believe it's installed / updated properly yet. What I've Tried Inserting new maps version disc to upgrade When I do this, it does not fix the issue. The only difference is that after showing the Lexus logo, the screen shows "Please wait while system updates" for about 3 seconds (each time i turn it on) and then goes to error. I got the same results with versions 10.1 and 13.1 discs so tested and found out that it shows the same "Please wait..." message even if an audio CD is in the drive :) (Pics at end of post) Resetting NAV Unit via Battery Backup After reading a post (on this site, i think) I removed the NAV unit / DVD drive from the bracket under my passenger seat. I opened it up to reveal the drive as well as the battery backup (with yellow border.) The instructions said to drain it with a light overnight. I simply removed the battery for about 5 minutes. I re-assembled it and hooked back up. No change at all The next night, I opened it back up and drained the battery via light method as well as leaving the battery out overnight. I reassembled and still no go when trying to Original, 10.1, or 13.1 discs. Below are pics of the NAV Unit I removed. Included are the cables connected to it and model number. Is this the box I'm supposed to do this to or is there another? (Pics at end of post) Resetting NAV Unit via Ribbon Cable I've read that units may be reset by unplugging a ribbon cable for a few seconds - but - don't know if this pertains to my unit or not as the ribbon cable was difficult to get to and seemed to be the drive data interface. Still, removing the battery should have had the same effect. Perhaps I'm doing this on the wrong box? Another Secret Menu I cannot currently access the secret menu I had previously where I made the stupid mistake. I did find out about another today, though. Holding down the Info button, turn the lights Off, then On 3-4 times. Unfortunately, this menu doesn't have the same options therefore I can't change anything back (even if I knew what to change it back to.) It does have a "NAV Reset" option, but it's greyed out. So - that's where I'm at. I can't afford $1000+ on new hardware and would really hate to do so. Any suggestions? I'm willing to try anything to fix this! Thanks! Pics
  2. Good Morning All - As of recently, I am the new owner of a 2003 GX470 which I love! Prior to this, my favorite vehicle I've owned was a '98 Land Cruiser so even though 2003 is still older, it's still an upgrade for me. :) Being very much into technology, it's unfortunate that the only media options which came with mine were FM/AM Radio, Cassette, and CD Changer - no MP3, Sattellite, iPod or Bluetooth. I'm trying to upgrade these items - and have done so successfully for most - but still haven't gotten to 100%. The other thing I'm curious about is the Navigation options. I found out that my unit is a Gen3. I've read in various forums that I could upgrade to a Gen4 unit by literally unplugging the old one and plugging the new one in. If legit, I'm not sure if it's worth the hassle, though. I decided to post and see what suggestions you could give me, please... Yesterday, I installed a MediaBridge (MBR-1500-TOY) as it should have resolved all issues. The MediaBridge is built to plug directly into your OEM radio and add support for Bluetooth (MP3 & Phone), USB, AUX, iPod/iPhone/iPad, and SiriusXM radio. Installation is easy as the hardest part is taking the paneling apart. Unfortunately since I do not have an OEM Satellite or MD option, I had to disconnect the CD Changer to hook it up. Once I tested it, everything worked - except SiriusXM - even though I had the extra required tuner hardware attached. After research, I found out that seemingly SiriusXM only works if my OEM radio already supported Satellite. So - Here are my questions: - What is the best solution that I may add to the MediaBridge which will provide Satellite radio? I'd prefer something in the dash and not an additional exterior component - Is there an option / device you suggest which will replace my MediaBridge and provide Bluetooth, USB, iPod/iPhone, AUX, and Satellite? I've seen the ones that add iPod only, but some I've seen are the same price as the MediaBridge - Anyone know of a Software Update or firmware to potentially add SAT mode to my existing OEM radio I know I don't have the hardware and it wouldn't work OEM - but - if I could emulate SAT mode and control the MediaBridge though it, then it should fix the issue - Assuming I could potentially upgrade, is there a dramatic difference between Gen3 & Gen4 Navigation systems? I've tried to find details online, but can't. I think that's about it. If you read all of my long post, then congrats and thank you. Any suggestions are appreciated - Thanks so much guys!
