Hello everyone!!! I have had my 04 GX 470 Lexus for about 3 months now and I just noticed that I can setup different dates/miles required maintenance on my Nav system. The only problem is that none of the buttons are highlighted so I can't enter any of the dates for oil change, tire rotation, air filter changeout etc.... Any help out there for this option? thanks for any and all help!!
