2007 bmw x3

Crutchfield customer from Lafayette, IN on 9/19/2021

2007 BMW X3

Verified customer (What's this?)
Verified employee purchase (What's this?)

I cut this harness in half to make a jumper for 2007 BMW X3 worked flawlessly. My factory radio was creating a draw and Bluetooth did not work well. I am a bmw technician at local dealership in lafayette Indiana. Was unwilling to cut wiring on vehicle so this was the solution. Alpine single den radio and mount. Got extra screws for mount as it only came with 2. The steering wheel control module did not work. Contacted crutchfield and module company neither was much help but other company did send me easy to read wiring schematic
