Pros: Text-to-voice spoken directions. Intuitive user interface.
Cons: 1st unit lasted 8 months being used twice weekly. Replacement unit lasted 8 months under identical use. Both units displayed identical "symptoms" before dying. Have also had two car adapters quit working over the same time period.
Cons: Need to fix bugs in software which causes problems with getting to your location - NOT a good thing when it comes to a navigation unit! I went with Garmin because of the reputation, but this one is just awful.
