Hello I have a 2002 330ci with the HK system.
I am wanting to replace JUST the factory HK head unit with a Alpine
Does anyone know if this is a simple "plug and play" proceedure?
In other words, is there any line level conversion that needs to be
or can i just use, say for example, a crutchfield wiring harness?
Also, any info on faceplates would be greatly appreciated!
