As I mentioned, I have yet to load the upgrade (advertised from the dealer at $300 w/o lockout) but the only system requirement seems to be an existing Gen 5 navigation system installed. I suspect the 2008 has that generation nav. The disc is not OEM.

Non-OEM software that upgrades and allows override (safety features) and use of the navigation system while in motion as well as bluetooth functions and viewing DVD's on the nav screen. I have not installed it yet. I have not checked the current nav version as it came installed in my 350 from the dealer. It was the latest at the time of purchase so I suspect it was the last update before 7.1

Blaise - I just posted a request for help installing a 7.1/Gen 5 upgrade with a lockout that allows navigation inputs and use of bluetooth while driving. If you can help me with installation maybe i can help with the software to solve your problem. Let me know.

I have an ES 350 with a Gen 5 navigation system. I have a 7.1 navigation upgrade with lockout but am unsure as to how to go about installing it. Any instruction/advice /suggestions would be greatly appreciated. Thanks.
