Car stereo install, no audio or audio only works with tuner...SOLVED
 

I installed mine today.

You follow all the colors on the harness but you must not connect the blue and blue together.

Here's the info you need to save your hair when installing:
stereo unit to Harness
Solid blue to WHITE
Blue+White stripe to Solid Blue

It's almost like they do it purposely to mess you up!
Had I known this, the install would of taken 1.5 hours instead of 3

Quite a tough install..
It took me 3 rounds of at least 1 hour and a lot of cursing.
Even when you got everything working...you're still screwed when trying to put it all in!

I had to cut off anything unnecessary from the back of the uint..Like 3 pairs of RCA? connectors... Jammed all wires and harness in a pocket deep inside first with bloody hand, then forced the unit in till I heard the "click"
Ahhh... the sound of success.

You owe me a beer.

Where did you connect the RCAs man? I popped out the radio and there is some wires.. but i also know there is pre-wired amp for a BMW Cd player in the back. I saw a video showing how to install but still confused because the guy never made it clear what wires he was putting on there.

Any advise would be good. The RCAs/output is the only problem i have..

you don't need them. all the wires that come out of the stereo connect to the harness. I got my harness through ebay. I actually cut them off cause I needed the space.

Do you wire the harness on the tuner with the HD input for the amp.. And the harness is the one that is in the back of the stock radio right? I'm not good with the names haha

i know this is a old thread, but you saved my ass when hooking up my indash tv, thanks man!!

If you wire the system this way, what about the extra wires?

What about the Stereo White and Harness Blue+white stripe? Do you just cap off those leads?

you connect it to the other blue wire i belive...

Does anyone actually know? I mean is this set up for the 'standard' head unit upgrade replacement? Is it with or without the optional AMP?
