I'm new to the Lexus RX400H. I've read the manual, but unfortunately it does not have a troubleshooting section.
About a week ago, the GPS unit would not come on when the vehicle starts. It just flashes up with the Lexus sign now. While this is happening if the radio is on that goes up and down in volume in line with the flashing. The Air or heater won't turn on at all, I can not access any of the menus for the screen/map. All other dash screens work and other electrics.
Any ideas?
