Navi Help needed!! retro fit!

[goldysingh]

Hi all, firstly what a great web site, i successfully completed a retro fit nav system with tv on my e38 with help from the manuals and info on this site.

I have managed to install a complete nav system with t.v system but have encountered a small problem, NO SOUND!!

I have sound from my cd changer but no sound from my t.v or nav system, i think i know what the issue is but need some assistance.

The loom which i have installed in my car came out an accident damaged 1998 car, mine is a 1997. The loom fits perfectly and all of the components works well. I have a normal bmw amp (non DSP), the speaker wires that come out of amp have two bunches of wires, a blue bunch and a yellow bunch, total of 8 sets of 2 speaker wires (8 outputs in total) but my existing loom for the speakers at the front of my car only has 4 outputs.

does anybody know what colour the wires coming from the amp for the tv and nav system? I can hear a slight noise coming from the speakers when the nav system when it tries to talk..but no voices!!

please help!

pics of wiring can be found here...
