TomTom - One GPS Navigation System Review

I purchased the TomTom- One Third Edition over a year and a half ago and have used it many times for for long and short trips and sometimes just to determine the best route to somewhere and the estimated time to get there. I love this device. I still haven't used all it capabilities but I am still learning. It is simple to use and it is interesting to see your trip in progress as you travel. you know where your are, your speed and estimated time to destination. The only problem that i have had with the gps system is the short battery life. You don't have long if not plugged nto a charger. I had looked at several gps units but decided to buy the Tomtom due to the rating I had seen it get. Wish i had bought one sooner.
