When I bought the car I was told that it had an upgraded COMMAND system fitted and thought no more about it - that was 6 years ago! I recently thought about loading up the CD player for a trip and pressed the silver strip button below the hazard triangle, but the door did not open! First thing I did was look up the appropriate fuse (No 26 located in the drivers side internal fuse box) and it was not there! I did not have a spare, but upon reading some threads here, I noticed some say that the upgraded COMMAND system negates the door's operation. Can somebody please explain this to me - with a fix if possible? Many thanks in anticipation.
