We were getting set to go to specialty store some 15 miles away, mostly freeway driving. Wife handed me address for Nav. When Nav finished calculating 'fast' route, gave a verbal warning about slow traffic along the route. Last thing I want to do on a sunny Saturday afternoon is sit in traffic. Then I noticed a 'Detour' selection highlighted on the iDrive screen, so I selected it. Nav guided us along a scenic alternate route - one that I would not have thought of. On the way back Nav guided us along the freeway (no slow traffic coming home). Sure enough, could see heavy stop-and-go on the other side of the freeway. iLove iDrive.
