Hi All,

just retrofited my E53 '05 (just had business cd/MID + BT) with a Sat/Nav MKIII (yes, i will eventually upgrade to a MKIV), but I am having the following issues:

1) No Phone AUDIO or muting of Radio
2) No Nav Voice

So, I started to inspect the cables and have worked out the following
1) I have to run a second MUTE wire (from another post) but I dont know where from/to
2) I think the cables are in the wrong "holes" on the connector.

The kit came with a full wiring harness, rather than the retrofit cable.

Looking at the connector that plugs into the Radio, 90% of the wires have been cut and joined (dont know why, but its all the ones on the small Black and White plugs).

I have checked the connections against this and most of it is correct, except the Phone Audo +/- and the NAV/TV +/-

The phone coloring is mentioned in the link above, so I found that those two connectors were in 5 and 11, rather than 6 and 12 of the Black connector, although this still didnt work until I find the "other" mute conenction. I am sure it is the mute, as when you dial on the phone, the Nav Screen shows you are in a call, but the RADIO (or other sound source) is still on, rather than the phone audio, which I am presuming the PHONE ON cable is connected, not MUTE (Please correct me if I am wrong).

And that leaves holes where the NAV/TV wires should go.

So, what I am actually asking is just the color coding of the Nav/Tv +/- cables as this is NOT in the link above. I have searched to the point of doing my head in. I even looked at WDS, but that doesnt have the conenctor mentioned in the above link (x13649).

What I think I can determine, they are Blue/Red and Blue/Brown, but then again, the speaker wires are that color too..

Can anyone help with the color of the NAV/TV wires and the "other" MUTE

Thanks,
Rob
