Pros: Screen is easy to view, and voice directions are easy to understand, though it tends to get drowned out in heavy/noisy traffic, even with the volume setting at maximum.
Cons: User interface is tricky at times; battery life is short; battery cannot be replaced, easily (there's a big rigamarole you can go through to do so (see summary), but, if you only use it while plugged into your car lighter, then there's no problem).
Summary: disappointing. lots of poi not avaible. for instance, no grocery stores or starbucks. if you try to type it in you can't.it anticipates after 2 or 3 letters and comes up with something completely different. easy to use but limited poi.
