Do not purchase BMW Navigation Update! TomTom is terrible..
My folks just retired and purchased a 2012 335xi! During a recent visit, my father had the Navigation Update for their car installed and the TomTom maps used by BMW are not accurate for the Washington Metropolitan area. The system gives inaccurate directions for addresses in DC and in the Maryland Suburbs. My older 2004 330xi that uses Navteq CD based maps is able to find the same places without issue! The new BMW navigation update is so bad my father went out and purchased a Garmin at a Best Buy during his visit. I also loaded Waze and Google Maps on their phone as a backup.
My folks are pissed and have already contacted BMWNA and their credit card company to rescind the charges for the update. If you're considering installing these maps, please reconsider! It's a waste of time and $$!
