  1. I made a strange discovery this week. I installed a version 7.1 map disk in place of my 6.1 disk and, or course, the "I Agree" thingy went away. Then I temporarily removed the 7.1 and reinstalled the 6.1 disk and the "I Agree" is still gone. Has my Lexus learned something from the 7.1 that it remembers?

    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).

    It shouldn't operate on the 6.1 disc once the 7.1 disc has been inserted...

    You can revert to older dvd's. I believe the only time when you can is from a newer dvd to version 0.1.

  2. From my understanding the latest version has a glitch in it. If I were you I would wait until October when the new version is released. You dealer can tell you what new stuff has been added when it is released before you purchase it.

    Do you care to elaborate on this "glitch"? This would be the first I've heard of it.

  3. That would be handy for many here. Can you post them for everyone?

    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).

  4. The cost of a loaner (for warranty work lasting longer than a day) was already priced into the what the OP paid for his new Lexus. He shouldn't have to pay any "surcharge."

    @Randy&Bonnie: Actually it does specifically state that Lexus will provide a free loaner in the warranty. Yes I agree that $5 is a small amount, something the OP is not disputing. I would say it actually reflects more poorly on the dealership charging $5 though, than someone asking why they were being charged $5.

  5. You would need to get a generation 4 navigation dvd for your 2006 GX470.

    The navigation drive is located under the front passenger seat. I would recommend sliding the seat all the way forward to get the most room.

    The latest version is 8.1, but you could save a substantial amount of money getting an earlier version like 7.1. You should check the updates included on the 8.1 to see if it is worth it.

  6. As of this post I only know of Step Hen that was successful getting a 5.1/8.1 hybrid working but don't know about on an 09 RX.

    Tried my hybrid 8.1/5.1 disc in a 2009 ES but it didn't work, so it's back to the drawing board.

    Lexus must have changed the 8.1 firmware to not allow any downgrades. That's my story!

  7. Is it very common that the drive won't read a burnt disc?

    Do you know where one could get an original disc for less than what the dealer wants?

    I've only seen the problem in generation 2/3 drives, especially in the earlier years. Perhaps the lenses back then weren't as strong or reliable as the current ones, or they have deteriorated over time.

    If you're looking for OEM discs, I would say ebay or craigslist would be your best bet.

    I have an OEM gen5 7.1 and an OEM gen4 5.1 that I should put up for sale soon in the classifieds.
