I am in the process of swicthing dashs from my one SD that I'm not driving to my SE.I have the dash out of the SD it took me close to half a day but I was working without a manual and had to figure out the normal MB tricks (they use a lot of the same logic on all their trim parts. The 123 should be similar.I think it's worth the effort for a nice dash and a good time to inspect vacuum system and wireing...........
