Bought this Dice setup at least a year ago or more, tried to install and had no luck. Just recently did a complete rip and replace of the system in the Z4 so this will never be used. I did discover as I had the car apart that the DSP connection I was supposed to use was by the passenger side sub.
This includes the Media Bridge, the DSP adapter and cable, and the cable to connect to the Z4 harness. It also has a long USB extension cable. As I never had this working I CANNOT guarantee that it works.
I'd like to get $100 + shipping out of it.
