Post E46 Radio X18126 Wiring Pin Out Chart

E46 Radio X18126 Wiring Pin Out Diagram Chart

I haven't seen this elsewhere in the Forum, and thought posting it would help anyone upgrading to Nav or altering their radio sytem to an after-market unit.
Although I formatted it in plain text, I am not sure how to get this website to retain the column spacings - it seems to eliminate all extra spaces.

Looking at the face of the (illogically) numbered radio plug in the dash:

[blank space] --1
[blank space] ------2
5 ------4------3

The stated pin numbers for the dash plug are different than the radio plug.

Looking at the remote trunk radio, or the back of it's plug:

4---8----12---16 10ampfuse

Dash Radio
Pin# Pin# / Use / BMW Color / ga. -----Universal Color

1 --3 LF (+) yellow/red 18 ---white
2 --2 RF(+) blue/red 18 ---- gray
3 --4 LR (+) yellow/black 18 ----green

Other Universal Uses: BMW(if used) --------Universal

These are from my Haynes manual and the Nav Retrofit kit wiring diagrams, and various websites.
Please help me fill in the blanks and the question marks!
Let me know of any corrections, clarifications, or additions.
