I have the same problem with this one-ZENEC NC2011D modell car radio that iGO GPS navigation is not synchronized with the time on the clock radio! Or 10 hours time difference it!
The file sys.txt great differences in the time zone tried to enter, but the problem is not solved!
I would like to ask you that this problem has been solved or is still some way to get the problem still exists?
I look forward to your response!
