My house which was built 5 years ago doesn't show up on navigation. The system needs to be updated.
Navigation screen goes blank. Misses turns or does'nt tell u to turn until it is too late to make turn. Has not been repaired.
Take forever for the heater to heat up..what's wrong with it?
I have a 2009 Lexus ES350 and on the naviagtion screen there is a Diagnosis check 1 displayed on the screen that will not go away. You are not able to control any navigation controls on the screen such as heat, map, bluetooth, and satelite radio.
