The C310 is an entry level model that is reasonably well priced for what it offers. First time users may take a while to grasp the bells and whistles of navigation, but otherwise, this is a solid unit.

A solid option that is fairly well priced considering the features offered. The iCN530 is a good choice, but keep in mind that some of the newer Navman models offer refreshing interface changes and newer map views.
