Z4 M Sat Nav - Help !!!

[snowfish]

I have been trying to work out what i need to do to get my sat nav to use a latest disk. There is an overload of info on the z4 and x5 forums!!

- Is it an upgrade to 31 or 32 ? (what mode/form do i need ?)
- Are there any simple instructions out there in one place (rather than trwling through hundreds of posts)?

I have also been trying to understand what disk version i need, is it the HIGH and not the PROFESSIONAL one ?

Any more info and tips would also be gratefully received.

Thanks for your help guys, dont want to wreck the system by rushing in
