e39 headunit circular pin to straight pin adaptor

Recommended Posts

My e39 standard cassette headunit went kaputt so I went to scrappie and bought a replacement headunit, however the pins on the replacement unit are circular pins and the connectors on my car are straight pins, unfortunately I can't get a refund on the stereo so is it possible to get an adaptor to fit or not?

Thanks in advance.

Dealers sell them for exchanging older round pin radios for newer flat pin versions.

You'll probably need :

61.12-6 913 957 - Round Pin to Flat Pin Main Radio Adapter

This is the main harness plug for your radio. Your car's original radio has a main plug (with round pins) and two 10-pin audio input cables that integrate with the main harness plug. The new radio you have has a flat-pin main harness with two 12-pin audio input plugs that integrate with the new main harness.

61.12-6 924 785 - 10-pin to 12-pin radio audio input adapter

This converts the original 10-pin audio input plugs for your original radio into the 12-pin plugs that the new radio expects. You'll probably need 2 of these.
