Garmin Constant Power Cable
Garmin Constant Power Cable
I used the Garmin Constant Power Cable to keep my dashcam recording even when the engine is off. It’s super simple—plug it into your car’s OBD port, connect the USB to your dashcam, and choose 10 minutes, 24 hours, or infinite. For me, the best part is being able to switch modes depending on where I park.
