had nothing but trouble with the wireless set up. admitted it was used daily two or three times back and forth to work, parking up etc. mine was on my wince unit from sean radioguy and the wireless setup. so i cannot really say if it was a quality issue or not. i went through 3 transmitters and 2 receivers ... all from sean. the other thing i noticed was the lack of connection and sometimes none at all if someone or something was in the middle rear seat. sometimes just an outline on the screen ,until the person or whatever was removed from the rear seat area. i hardwired mine and never any problems since. i went through the boot lid flexi wire into boot then down and along under carpet edge and eventualy into the dash on that side. half an hour to do once the boot lid was sorted. so still all good now im happy to say. ...
