I was amazed at how easy this was. All it took was simply popping a few panels off and removing 4 screws. It took about 45 minutes total. All functions worked seamlessly including my Sirius/XM (new unit came programmed to my VIN). Sync 3 with CarPlay/Android Auto is far superior to Sync 2. My only regret is waiting this long to upgrade. It changed my entire driving experience. I would certainly purchase from All Things Sync again.
