Hello, I was doing on a full detail for my 540i I just picked up and I came across a module that's obviously aftermarket. It's plugged into the harness in the left rear with all the Nav and phone electronics. No idea what it is or what it's supposed to be doing.
The writing on the module is not very legible, but I can make out Road Rage Automotive Audio Systems. I did several Google searches, but I wasn't able to find anything related to Audio.
Any ideas?
On another note, it was super weird that I found both a Argos Bluetooth box for wireless phone connectively and I also found an ISimple bluetooth module as well that seemed to only add an aux in cable for the prior owners Iphone. I pulled the ISimple module since I don't have an Iphone and also just to clean things up.
Thanks!!
Road Rage Audio is based in Missouri. The component is likely an amp.
change before but dont use that options
