tangalife 1 Report post Posted July 19, 2013 So I dont have the loom plug in my car, which sucks, so does my new head unit have to be hard wired in? I have the 4:3 nav unit double din. 1997 E39 540i.

Been a huge mission sorting sounds out for my car Be aware that when you remove the nav system you loose the ability to adjust and set Date Time Trip Computer Security Code (and more, depending on what options are fitted) All speaker wires are in the rear of the vehicle, you will have to run speaker wire from the front to the rear.
