Yes because the BMW iDrive Nav GPS (sharkfin) antenna is outside the car, where as a Garmin unit uses its own built-in antenna (so if you use a Garmin or whatever, it will have slightly poorer GPS satellite reception).
I always have my ipad to supplement my idrive for direction,i wonder if any in here has garmin sticking on the windscreen while the idrive is showing direction..

Yup! BMW navigation is not user friendly with many areas not shown although i have got the latest version and I still can't find roads i see very clearly on Googlemap. However, I do find the other i-drive functions very useful.
