Sync 3 clock issues

Done the Sync 1 to Sync 3 swap about a year ago. Only issue I’ve had is the clock won’t allow me to change the time. I’ve spoke with NaviUpgrade’s and suggested trying a new APIM. Swapped out the APIM and clock worked fine until my car battery died. Now it’s back to the usual. Just force resets whatever time I input. Says GPS reset is not available, so we tried a new GPS antenna and nothing. Any suggestions would be helpful. Oh and we tried changing the input value’s in the asbuilt too.

Maybe post you APIM AB here and see if it is just a setting.

So I reset the clock value from 21 to 28. And it allows me to finally change the time. Let’s see if it decides to work this time.

Your car is CGEA 1.3 so that’s the right change.
