I have been having a few issues with my new used car, and the radio is sadly giving a few errors, and we have tried resoldering the joints, but sadly this didnt help alot. So I looked at buying a used one of eBay, sadly I am having even more issues with this one, and here comes my question.. If you have a BM24, does it then matter, if it is the old BM24 radio module (no black heatsink, but round pins) or the new one with black heatsink and round pins?

I currently have the newer one installed in my car.

The one I bought of eBay has part # 8363142
