Car is 07 Corvette with swc. We switched out Factory NAV for Kenwood 6960 and PAC SWC Jack. Everything worked fine until after driving car for say 15-20 minutes and then SWC function would stop working. The installer switched out the PAC SWC Jack and reprogrammed with battery at full charge. Same issue. I exchanged Kenwood 6960 for 6990 and still same issue. Any ideas as to why this might be happening?
I have no reasonable clue of why this maybe happening, but I personally recommend using axxis aswc module over the PAC one, it auto programs to your vehicle so you wouldn't need to program each and every button seperately, also it comes with a kenwood specific plug that's designated for seamless programming, I know I didn't answer your question, but an alternative solution is never a bad idea either
