How Easy To Install
 

I have Just orderd a new x5 and and i am kicking myself because i didnt get the sat nav. I rang the dealer to get it put in but they said it was to late has it was already being built to my spec. How easy is it for me to install i have read the instructions on this site and they look complicated.

call the dealer ASAP to see if you can get a 'do over'. Retrofitting NAV takes a lot of time and effort, and you're better off getting an X that has NAV already in it.

do a quick search to see what it entails, but you're looking at $5k+ in parts and many, many hours of headaches.
