If you've replaced the entire system, make sure not to use the BMW supplied ground wires from the harnesses, make your own. Use wire equal in size or larger than the power wire and attach it to a spot free of any paint. I use crimped on and soldered ring terminals.
Multiple audiophiles websites will strongly suggest every piece of equipment be grounded to the same point on the chassis to avoid loops, but I haven't found that necessary yet.

Hmm that would sound about right.
Just to clarify, I have changed the screen up front and connected it to the trunk with the long cable.
Interesting that I have not seen this discussed anywhere in any of the aftermarket stereo guides (or did I just miss it?). Is there any guide or recommendation on how to best go about this? Wouldn’t be a big fan of screwing up my cable and having to get a new one and redo the whole process of taking apart half my interior [emoji1]
