Excerpt: I like this model as it has exactly what i'm looking for. I purchased this item as I needed a Bluetooth connection for my car and I was also spending time in North America and this combined the two. Easy to use and sound quality is very good on the Bluetooth connection.
Excerpt: The Sat Nav itself is very good and friendly. I had difficulty downloading the required maps and software. The software which does this took a long time and never actually said that it had finished doing the job.
Summary: I purchased this unit for a European Trip; since I already had the 2557, I assumed the 2577 would be more than adequate. I was incorrect. On several occasions the icon would not even track on the road; inaccurate directions occurred about 50% of the time.
Pros: Typical decent Garmin interface. Crutchfield is, as usual, a pleasure to deal with and will pay for return shipping.
