Best praise vs top criticism for Garmin Dash Cam 47
“Easy enough to do yourself. I’ve installed a few over the years and the game changer for me was discovering that there are OBD power supplies. Mines a garmin and plugging into OBD port is a breeze and makes for a tidy install without tapping into fuses etc. Good luck.”
“I'm having the same issue and even after updating the Garmin 47 to version 3.50, my dashcam won't wake up after going into Parking Guard. I had to disable the feature altogether. Garmin customer service is utterly useless and can't figure it out. Needless to say, that's the last Garmin product I ever buy.”
