Should have skipped it and saved $30Update: the rear cam now causes the unit to crash on start up.

Video ends just before crash See pic's at 17:28:26 and 2nd video starts back up again at 17:28:48 after crash (picture cropped for

and when I put it back in my V1 would freeze on start up

Also, some of the 3 minute segments start with about 20 seconds of glitched video; it's not that bad but seeing squares in the video jump back and forth through time while it starts the new segment is a bit strange.

Thus far the replacement has work as it should

Easy to set up and install (as well as to hide the wires)

I enjoy the expert firmware on it as it has added features

Good A+
