Not sure about the newer ones but mine is the original WinCe 5 unit and I had the front off mine this morning.2 screws on the side and two on the bottom,pull off both knobs and slowly pull the front away from the main unit.It is connected by a straight multi pin similar to this with the corresponding socket on the main unit.
and a ribbon cable which can be released from the connector on the facia to completely remove the front.
