OK the headunit is swapped Wow, what a difference the biggest and best improvement for me is the bluetooth (includes phonebook transfer) no more fiddling with divert codes. Just get in start up and go, the unit it's self has Radio, GPS (really excellent full European 3D maps and post code search speed camera and speed alerts) DVB TV, I-pod connection, plus it plays CD's DVD's has USB and memory card inputs (tried but not used) sound quality is great in all functions and steering wheel functions are retained. Just to much to mention really and all for less than the cost of upgrading the BMW phone system to bluetooth. The car is still going well, I have been onto a number of shoots recently where mud has been a big problem but the X5 has got us around and not got stuck (yet), even drove around a stranded Disco (I think if I had stopped there would have been two of us) He needed two Landrovers to pull him out.
