i have an extened warranty to 150,000 miles with continental, they cover the nav system, bmw does not. it cost me $3400 about the same as the BMW warranty to 100k, it also has no deductible, i think BMW has a deductible.
i was worried about the 100k mark, that seems to be a point that a lot of BMW's need a refresh on a bunch of parts. Radiator, water pumps. and i am always concerned about those turbos.
