What is the DVD disc in the vehicle? It needs to be an 86271-3303(2 or higher) to be compatible with your vehicle. If it is an 86271-3304(2 or higher) the DVD disc not compatible with the DVD unit in your vehicle.
Lastly if the correct map disc is installed the DVD unit has failed. I am not aware of any authorized repair facilities in the US. The DVD units are sophisticated hardware... the only other option would be to pick-up a reman unit from a Lexus dealership. If that doesn't appeal to you there is always the junk yard. :(

The DVD that is in there is 86271-33032 - the right one. Thanks for that info. Before I go to "toast" status and buy a reman from a dealer I would love to go deeper. I bet this thing is expensive, right? Eeeeeeeeeeeeee!
I am not an auto tech but I am a computer network tech. Is there anything else I can do myself? The unit "looks" to be working correct in that a) the optical laser lights, B) the disk spins up, c) the disk is read (it can tell a program disk from a fake), and d) the DVD reads perfect in my pc.
If you (or anyone else reading this!) has any ideas - even some long shots, or knows of a repair facility, I would be very appreciative and would owe you a few beers and a few tequila shooters and probably dinner when you come to Southern Idaho. I would also be open to paying someone to advise me if we could get some results.
Again many thanks. Jim
