I read an article in one of the car magazines comparing both Tom Tom and Garmin. They are pretty close, with each one having small benefits over the other in different areas. What swung me was a client of mine who lives in the UK travels to Ireland regularly and he used both and said the Tom Tom was better. However, you need to compare Apples to Apples, as an entry level Tom Tom is inferior to a top end Garmin and vice-versa. I would definitely stay away from any of the other generic brands. Stick with either Tom Tom or Garmin and I would recommend getting a larger screen if available. My Tom Tom got me through France on a 3 week tour and paid for itself just on that trip. Yo also need to make sure you keep the software updated and get European Maps up front if you plan on using in the Continent. I found Tom Tom customer service very responsive in dealing with one small software glitch I had within the warranty period. Good Luck !
