In my work, I have an approximate 60 to 70 mile radius that I work in. Every day I am in a different area. My TomTom is one of my most useful tools.
When I first got my TomTom, I did have trouble with the device finding a satellite signal. I finally called the technical service department at TomTom and they took me step by step through troubleshooting to get it to work properly. It basically had to be rebooted to clear some errors that must have happened when I first downloaded the maps from my computer.
The TomTom One 125SE model I own has a 3.5" widescreen and comes with a mounting device that attaches to my dashboard. I can easily remove the TomTom from the holder and tuck it into my purse, to prevent it being stolen. It also comes with a car charger and the USB cable to connect to your computer.
The TomTom is very user friendly. Once you download the maps from the TomTom website, you pick a voice that you like from the menu and your ready to go. When you enter an address, it will show the map with street names and arrows that guide you along. In addition to the visual map, you also have the spoken directions guiding you along. The spoken directions will alert you to your next turn and how many miles or yards ahead that turn is. It tells you how many miles to your destination and approximate time of arrival. You can even turn on a feature that will alert you if you are exceeding the speed limit.
There are times that the TomTom will take me a slightly longer way to the destination than could have been taken, but all in all, I am satisfied with it's operation.
You can get updated maps online and lets you download one complimentary update to the map during the first 30 days of use.
Another great feature is the preloaded points of interest to gas stations, stores, restaurants, hotels & other destinations. I have used this successfully several times to find gas stations and stores when I'm out of town. There is a Help Me emergency menu to access police, fire & hospitals.
I won't go anywhere without my TomTom!
