Query: Very Easy to Setup and Use

I would recommend the C320 as a very practical and economical auto GPS device. A word of caution, as with any automated mapping product, you should validate the general route prior to starting your trip since you sometimes are taken on longer or highly trafficked routes.Notables--The setup is very easy.-The device can be used without consulting the manual thanks to well designed menu screens.-The suction cup that holds the unit to the car winshield locks on very tightly.-The screen is smaller than units sold with most cars, if you want to view a route or follow along while driving, this can be a bit of a problem. I use the voice prompts and rarely view the screen.-The included memory card can hold roughly 2 states worth of maps. That is more than enough for me, but might require an upgrade for others.
