Hi guys, FNG here. Just wired in the gerbing harness for heated clothing. At one point when I was attaching the hot wire to the battery terminal, I heard the Garmin beep (factory nav) and it came on. Tried many times to turn it off with the switch, but this only kicks it into a program having to do with volume for the stereo and the nav unit itself. Has been on continuously for at least 30 minutes. How do I make it shut off so it doesn't drain the battery? any help is much appreciated
