So I'm going to post my install here, hoping it will help you (themoth) or atleast somebody down the line.

I have a 2002 X5 w/o navigation w/ DSP. I ordered the DICE DSP adapter and the DICE MediaBridge (MB).

1. I first installed the DSP adaptor via the following:

-Power wire soldered into purple/white switched wire (as recommended by EAS) from the SES jumper bundle (it can be found adjacent to the CD changer plugs in the rear left compartment).

-Ground (earth) was run to a taillight bolt (directly to the chassis).

-Coaxial cable from amp directly to DSP adaptor (was a pain to remove the end from the amp!).

2. Next I installed the DICE MB as follows:

-The 6-pin plug from the CD changer was plugged into the MB.

-The RCAs from the DSP adapter turned into a 3-pin connector which was plugged into the MB.

-The MB 1500 bluetooth microphone was run to the front of the cabin under the carpet.

The MB MIP switches were set to the correct settings via the manual (I believe they were alternating for my MID headunit).

Voila! Excellent audio quality. I'll grab some pictures when I get a chance. It's no fancy install but it works perfectly.
