Hey does the Nav System play DVD's also?
I have been told several times the 2007 Tundra Nav system is a 5th gen, are you sure it is a 6th gen? Is there any documentation that spells that out?Not the gen 6 system that ships with the 2007 Tundras. The gen 5 system could be unlocked to play DVDs using a hidden service screen. It is possible to downgrade the unit to gen 5 (the hardware is the same) by building a DVD using the gen 5 firmware. The Lexus forums have info on this process, but you would need to borrow a gen 5 DVD from someone.
