Great GPS Unit

I purchased this unit before a trip to the UK last year. It has worked beautifully since. I was able to purchase an SD card with full UK maps and it never missed a turn, even on back roads and in the Irish countryside. As for the US, never a problem. Since my unit has never had an issue I have never had to deal with customer service, however, Garmin is a major supplier of GPS units to police, military, and other applications.
I have found it easy to use, the screen is automobile grade and can be read easily in the bright light of day. In sum, this is one fine unit for the price.
