I am an italian newbee and this is my first thread,so hi to all.

I have a question for my 2003 X5.
I have not a nav system on it (I have a TomTom) but only the business cd radio;I'd like to have a dvd video system on it also with the use of mp3 file;can I install it with the possibilty to use the steering wheel control for mp3 file?
I have to remove the business cd radio? I prefer not because of computer control.

Is it possible?

Thanx,Marco
