i-Bus interface cable connection

[webpain]

Hi all! I'm a new Z4 owner (got it in January).

After I did some searching in the last couple of days, I could not find any information on where/how to connect the i-bus interface I got (to run NavCoder).

I didn't get the interface from Reslers, but on ebay and it looks like this:



Now I would really appreciate if someone would provide some info:

-Where is the best/easiest place to connect the i-bus interface (i.e. glovebox, trunk?)
-What are the cable colors in the Z4 (model specific?) for:

• i-Bus
• 12V
• Ground

-Once the cables are located, should I cut of a piece of the plastic wrapping and then just twist in the interface cable? Should I solder it?
-Any pictures/illustrations would be much appreciated as well as I would like to be sure what I'm cutting into so that I don't mess anything up.

I have already connected an AVBMW cable (for AV input) in the trunk and got it working, so pointing to the cables near that area would also be helpful!

Thanks in advance!
