suddenly my clock is no longer displayed on my GPS screen . . . have tried
everything and cannot get it back. . . .
I have had same problem and people here gave out the solution. If your car have a GPS you need to take out the SD memory card that is under the GPS screen. Click on setup, system, and click on rest to factory deafult settings. Wait 10 minutes and put back the SD card memory back into the slot. The system will restar and comes back and the clock it should work.
