Thanks Hank, I hadn't thought of this!
Over here, the BMW SatNav is a £2750 option and my car doesn't have it.
I'm not too bothered, I'll fit the existing Alpine unit to my G/F's Golf, she'll love it!
I'd much rather all that technology works!
A bit crafty of BMW though, as in if you want SaTNav, you only have one choice!
