Thanks for the reply.

I have now got the BM54. I will get the MKIV Nav Computer.
Do I need the TV Tuner to make all this work if I dont want the TV for now, and can this be added later?

I looked in the rear boot compartment, under the cd changer for the amp but couldnt see one, so thats why I got the amp, could it be located somewhere else, or is that the only place??

Shall I go direct to my BMW dealer in the UK to get the brackets, or is there somewhere online i could order them from?

Thanks again

Jon
