Hello fellow members, I am hoping that someone can help me.
I am due to book my car in to have the BMW sat nav sstem fitted and I think I have all the parts, but need to be sure:

I have the BMW sat Nav Monitor 4.3 display with cassette,
The Mark 3 Sat Nav computer (GPS)
The Complete Sat Nav wiring loom
The Tv Tuner for the e46 model and finally the GPS Antenner.

Some one said that I will need the BM54 Tuner in order for the system to work. Can you confirm this is the case, and if it is, does anyone haveone of these for a resonable price.

Hoping for a speedy reply

Thanks
