I just purchased a well loved 2010 V70 R-Design with a pretty basic option packet. I've also got a 07 S80 V8 that's loaded and really like the folding mirrors that come with the BLIS option. The V70 has the manual fold in outside mirrors so I've just purchased a Volvo mirror kit to change those to electrically folding mirrors, From what I've been able to research it seems this kit comes with both mirrors and switch. I do have the memory function for the drivers seat. My plan is to just pop the door panels off and plug in the new mirrors then take to the dealer to get the software upgraded to recognize them. Has anyone done this change?

You have two sets of the nicer Volvo rims! The V70 being similar to my old 98 S70 T5. It also looks like the S60 rims in the same years as your V70.

As for your model accessories, here is a link for Volvo installation instructions. There is one for "Door mirror, foldable".

I have two sets of the 18" Cratus rims that the V70 came with but they needed restoring so thought I'd use the 18" Odysseus rims instead. Have the Cratus on the S80. Thanks for the link!
