Review on 🚗 Ultimate Car Charger with GPS, Rearview Camera, and Backup Features by Dave Russell

Update: The supplier contacted me and refunded my money. I think the problem is that USB needs more power. Right now my job is to manually switch it to record mode and then it works. First review: My Garmin 35 DVR starts up in data transfer mode. For some reason, instead of just supplying power, the dash cam asks me to go into "mass storage" mode when I use this cable. I don't know if it's contacts or not enough power, but it doesn't work well with Garmin DVRs. If I press No for storage mode, the power supply works fine
