Pros: So many menus and settings, lifetime map and traffic updates, ability to do map corrections. traffic ability worked well in Toronto GTA area, not sure in other places. Easy interface when you play with it for few hours. voice command is not bad.
Cons: Lack Picture viewer, mp3 player, audio jack ,radio transmitter,and memory card slot. old fashion voice instructions. hiway image is confusing, the screen just mixes both bounds into one large road it looks like as if you are driving on giant tree.
