I just started on a 2005 Mercedes E-Class for a demo vehicle for my shop, anyone done an alarm in one of these yet? I did a remote start in my 2001 CLK, and that sucked like crazy, but this one is even stranger. Just a hint on the door locks would be a great help. Seems to be CAN-bus into the door control modules....in each door......hooray. Maybe someone knows of an interface?
