Jbl Head Unit Replacement

[chrisfarlow]

i have seen your posts on the forum and was wondering how people have replaced their factory head unit, i went for the jbl upgrade system but was a bit disapointed with sub output etc,.

i was told the car has a "multiplex" wiring loom and there was not as of yet a harness to change headunits. is this right?

Kinda of right if you checked out the MP3 ice thread i say in there how mine was done kind of. Rather fiddly though.

 

You will need a BMW type iso converter but it then needs to have a few wires chopped and hanged around a little bit.

 

Then you need a bmw aerial adaptor as well. i think it was a bmw type one.

 

Headunit pops out really easily and the standard jbl sub is probably ran from the rear speaker lines rather than a preout.

 

Took the guys in my local audio shop about an hour and a couple blown fuses to get mine right as its not the easiest change to do. Not had any issues with mine though i just cant turn it on without me turning the key like i used to be able to although theas probably a good thing i dont think the battery would last long with the power im pulling out of it.
