Theres a few threads on here but a few are american etc, i want to install an x1 in my 51 plate Mini Cooper.
I know ill need the Radio fitting kit from Mikey (iso leads, radio antenna adaptor etc)
From what i understand, you put the headunit in as any other headunit, there are then cables that run to a hideaway unit. Ive heard a good place is under a front seat, which ones best/easiest? How do i route the wires there?
I then beleive you have to link it to a speed pulse wire, which i thinks on the drivers side sill? and the reverse wire? and the handbrake wire? Then you have to place the GPS antenna, ive read under the dash is a place. Then thats it......what i really want to know is, is it tricky running wires to all these places?

Sorry for the long post. I have installed head units, amps, speakers in previous cars but navigation is new to me...
Thanks
