HD Rearview Mirror Monitor and Dual Camera System

I don’t see how this is a deal. I found it $10 cheaper at amazon.

The GPS feature is not clear. Can anyone confirm that it has GPS or at least connects to phone GPS via bluetooth?

Got one the last time it came up… Its great when it works, the problem is it tends not to work.

It has an input on top labeled “GPS”, there is no documentation with this thing on how to use it. Even the online docs (corrupt pdf and cheezy video “review”) from pyle are horribly lacking any info: http://www.pyleaudio.com/sku/PLCMDVR42/HD-Dual-DVR-Recording-Cameras-and-Rearview-Mirror-Monitor-System-with-Hi-Res-Video-Record,-Image-Capture,-Night-Vision-Illumination,-Motion-Impact-Recording,-(2)-Cameras,-Built-in-425-Screen-Display,-Built-in-Distance-Scale-Lines,-Parking-Assist
