Can you switch the standard sound to Harman Kardon?
Does Anyone know if you can or how hard is it to switch out the standard system in a 2011 to the Harman Kardon System?
I have been looking to get a new 2011 335i coupe but the ones I found at the price range have the standard system and everyone seems to think it is no good. I was thinking I could get the parts and install in my self or have someone else do it. Does anyone have any info or advice on that? I would assume the wiring is all the same just different speakers and amps etc.
Any help would be great.
