Where can I purchase a navigation system for my 2001 BMW X5 (factory or not)?
For a BMW navigation system, check out bimmernav.com. I’m a past customer, and there stuff works like it was installed at the factory, just like they say, based on my experience. But to retrofit a nav system you’re looking at a lot of money. You can get a lot of Garmins and Tom-Toms for the cost of retrofitting factory nav.
