I have a used BMW Auto Dimming Homelink LED Compass Rearview Mirror (Part #: 51167148839) and the Retrofit Wire Harness (Part #: 61120434330) that I purchased for my 2011 335i but never installed it. I'm looking for $285 shipped for both items. The wiring harness is brand new (paid $39 for it) and the mirror is mint. This mirror from the dealer is over $700. This kit includes everything you need to upgrade your old mirror to install this retrofit!
