I'm thinking about buying a Mini S 2005 or 06. My question is if I buy one without the Navi how hard would it be to upgrade to the oem navi? I mean are these cars pre wired for everyting like BMW's are cause I have a 3 series now and its pre wired for almost everything.

 

My understanding is NO , someone priced out the necessary components and the bill topped $2k ...
You can buy a flip up 7" with nav and install in stock location and be way ahead
