Guys, This is great stuff.
I own a 2004 330Ci convertible and a 2003 Range Rover. I have taken out the MK3 from the Range rover and fitted a MK4 unit to tie in better with the Beemer.
When I did this I lost the Off Road Navigation function that Landrover had activated in their software. I would love to get it back! Is this now a possibility? I'm sure X5 & X3 owners would be interested!
Equally is there scope for altering the colour scheme to a bespoke setting?

Can supply a copy of the Range Rover software if anyone is interested.
