I've been looking for a dash cam for about a month, looking for a dual channel where the rear camera mounts on the back window, not sure if there are crevices to hide the cable. needs to have GPS stand up to heat live in the desert. all the reviews I have read are promising and then you find the bad ones, some will say the camera is junk, poor customer service, ect. has anyone on the forum had good experiences with any dash cams around $250.00
