I change vehicles every month, (car dealer) and so I can't use a 3M sticky mount. Can I use a go-pro suction cup mount? I know this will loose me GPS ability, but would I be able connect the power cord directly to the Mini?
There is a micro usb connector in Mini itself, so yes you can connect it directly, loosing the GPS.
I'm not sure, if the go-pro mount will fit though, it should or so they claim in instructions, but there was some fitting problems earlier, maybe they have corrected it in newest versions of Nano Q. Please use search, there may be something in the forum, that describes this matter.
