  1. You can use Goo Gone on the residual adhesive, or warm water and soap. You may want to warm up the remaining adhesive with a hair dryer or with something similar first.
  2. Yes apparently Lexus has deemed Europeans as capable of operating the nav system while in motion while withholding this feature from North Americans. Perhaps it may also be due to the litigious culture in the US.
  3. Yes upgrading to a newer version will get rid of the need to press I Agree on startup (only with gen5 systems)/
  4. The newer firmware gets installed when you insert the newer dvd, and stays in memory. When you insert the older dvd, it sees that the current firmware installed is newer, and does not install the older firmware. So yes, the nav ecu "remembers" the newer firmware (so the I Agree button goes away). You can revert to older dvd's. I believe the only time when you can is from a newer dvd to version 0.1.
  5. Costco is the best when it comes to warranty and guaranties. I've had my tire replaced once due to a pothole, and there was no questions asked. It's nice that the warranty is included in their price. They measure the remaining amount of tread on the damaged tire and pro-rate the replacement tire. No worries and peace of mind!
  6. You may be confusing the dvd/cd changer for the dvd drive with the navigation dvd. They are two separate systems. I'll send you an email with more info.
  7. Do you care to elaborate on this "glitch"? This would be the first I've heard of it.
  8. By nav unit I meant the display. My mistake. As all wire splicing is done behind the display, I thought that would be obvious.
  9. Nope, hybrids no longer work with 8.1 in Gen5, and no longer work for 7.1 in Gen4.
  10. Which version do you currently have? That will mostly determine whether the upgrade is worth the money. It is mostly a map database update, with some firmware change depending on your current version.
  11. I could imagine the previous owner may have made some "adjustments" to the wiring to the nav unit. If you are out of warranty, I would pull the nav unit out and inspect the wiring. Perhaps there is a loose or cut connection back there.
  12. Perhaps a few more details would allow better diagnosis of the problem. Reason you removed disc? Where are you inserting the dvd? (into the drive in the glovebox I hope) Any error messages? Any other problems with audio system?
  13. Hey Tom, Didn't know I could host them in the post! Much easier as well. Edited my previous post to include the 8.1 updates in the first two pdf's, separated by generation. The third pdf is the 7.1 file with all generations found inside (quality is bad for the third pdf).
  14. I have the pdf's for the 7.1 and 8.1 updates. I'll send you a pm with my email address. Send me an email and I'll send them to you. That way, you can decide which disc is best for you. 2008CY_Gen23E.pdf 2008CY_GEN45.pdf Lexus_Nav_7.1_Update.pdf
