I have only had one problem with my lockpik since I've had it. It actually made my nav freeze. Had to pull the console apart and reset the power to the lockpik and it has been fine since.
This is the camera that I usedhttp://www.amazon.com/gp/product/B00...ls_o04_s00_i00
. IF you get one make sure that it is for front mount. The first one that I bought was for rear mount only and the image was mirrored.
