As a final comment, it's likely that many "similar" Mercedes modules could be swapped after a little (or a lot of) modification if one knew what wire to cut, etc. Unfortunately, I've never seen schematics for the insides of these things and it isn't worth the time to try and reverse-engineer the device.
