The routing on the Garmin was good. I do not have the car kit. Wish I did - I need a gooseneck suction cup for my windshield!
I tried Motion X GPS on my daily commute home, and the routing was terrible. I have it set to give me the fastest route, yet the route it gave me would've added another 10 minutes on my 35 minute commute.
I'll give it another chance, being 99 cents and all, but that was just severely disappointing.
