I used my Garmin with my last two vehicles. Its a good system, but IMHO, the navigation sytem in the MFT is far superior in its visuals. Plus, the MFT system has the ability to download driving instructions from 'points' entered through Syncmyride and directions sent from GoogleMaps. I really like those features. Its so much better than having to use the awkward keyboard on the Garmin to enter addresses and such.
Overall though, I really like the GoogleMaps on my Android. I wish that Ford could enter into some kind of agreement with Google to use their system in their cars. GoogleMaps is very nice, and is updated regularly (unlike Garmin or most car-based Nav systems).
