hello there, mate!!!
have you looked at this post too?
http://www.xoutpost.com/electronics/...-problems.html
first, lets see, what equipment you have: you mentioned a TV module.. is it an Original BMW analog or analog/digital (hybrid) TV Tuner module?
Do you have a factory Navigation system? you did not list the year and model of your car, so I would assume that you have an E53 with navigation - please confirm...
Are you able to snap some pictures of your equipment and post them?
The color of wires inside the car may not be as relevant, as the colors of the wire maybe different from country to country, from year to year...
If you have patience, we will get this thing up and running for you...
