In August I swapped out my SYNC 2 to a SYNC 3 upgrade kit, and it worked great everything worked and system ran smooth. Recently over the pass month Ive had battery drain issue (3.2amp draw) after pulling fuses I ended up finding that 4 fuses related to SYNC dropped the drain down to 0.004. has anyone had issues with their SYNC 3 APIM or is there some type of programming that needs to be done to prevent this? Any suggestions or guidance would be appreciated.
