Hi, I have a 2010 SLK 200k. To garage it we need to manually fold the door mirrors, so having power folding mirrors would surely make life a whole lot easier.
I thought doing a retrofit would be well worth doing so I searched for a thread on how to go about it, but couldn’t find one, I’ve also contacted my local dealership to enquire & they weren’t particularly helpful.
Has anyone out there actually done this upgrade?
If so, can you please help me with some advise, for example, does it require a re-wire or is the wiring already there?
can preface-lift car parts be used on the later facelift model?
& what coding needs to be done?
any advise would be very welcome. Thanks
