Ordered one of these through Amazon.com yesterday. Eagerly awaiting it. It will be my first Dash Cam, and I can't wait to install it in my Chevy Volt. Should be an interesting install, as the car already has a collision and lane departure factory camera, TPMS, keyless entry, and interior humidity sensor (for automatic interior defogging) up there in a large black box, just forward of the mirror. There's a light sensor on the back of the mirror itself, which I can't block. That would give the auto dimming function fits. Additionally, the Volt has opposed windshield wipers, which swing up from the center bottom of the windshield and out towards the corner. As a result the spot that many show their cams in could potentially be covered with a wedge of snow, ice, or heavy rain that the camera couldn't effectively see through.
Should be fun! ... It's a geek car, and this will be a geek task.
I'm going to use the static cling mount to try various spots along the passenger side of the ominous black box, then test drive to check for interference with the TPMS and keyless entry modules. There have been a few reports here and there of Dashcams interfering with them in generation 1 Volts.
Hoping to install it, set it up, and pretty much forget it unless it is needed. Hopefully that day will never come.
