I noticed that from the New Year (or 1-2 days earlier, IDK), my navigation shows the wrong time. Every time I switch on power the clock resets and start from +3 (I think because of the Auto Time Zone settings). What could possible be the cause? I tried to reset all that I could in the diagnose mode, and even re-download the navigation software, but the issue persists. Running out of ideas. Please HELP!
