Summary: I recently used the Garmin Nuvi 2577lt in Spain and it worked very well. The conversion from USA info to Spain info occurred automatically and seamlessly. The only caveat is that it is difficult to use in the old sections of cities where the streets are maze-like.
Good GPS with Europe and US maps but with no maps free updates
1 May 2015
Summary: I have used the Garmin 2577LT for sometime, it is a good GPS but lacks the free Map updates and the streets speed limits. The newer Garmin GPSs have the side streets speed limits posted in the GPS but for the Garmin 2577LT, the street speed limits are posted only for the main roads.
Summary: I was looking forward to this purchase as an upgrade to an old Garmin 3150 which had served me faithfully for 5+ years. Ever since I received this item it very often gives awful directions. You eventually get to where you need to go, but it takes you in circles, or makes other baffling mistakes.
Summary: I purchased this unit in April 2013, before it was even shipped to the retailers. I was going to Poland and Czech Republic at the end of April and I needed a GPS with maps of Europe, since I was going to rent a car and drive on my own. This unit was (allegedly) brand new to the market.

Summary: The garmin I purchased only worked for three months when the daylight screen would no longer light. The screen can only be seen at night. Considering the price I expect the product to last for years.
Summary: To all the people looking at Garmin GPS units: This one worked great on my trip to Germany. I had an old Garmin 255 and I love how this one is "instant on" when you push the button. No boot up required.
Summary: So far I've tried it out in the U.S. and Spain, with excellent results. The large, split screen is very helpful at crucial times when one has to make a quick decision at 120 kph. The range of destinations is very good; I could find obscure locations far outside the city very easily.
Nice easy to use unit; map upgrades and upgrading weak

Summary: I bought this to replace the 670 Nuvi that I bought in 2007. Like that one, I bought the 2577 as it came preloaded with Europe as well as North America maps. The good - the unit is much nicer in appearance and usage compared to my old one from 7 years ago. Makes sense as it should be.
