According to Amazon, Tomtom units receive an average review rating of about four stars. This leads me to believe that they are decent units, but could preform better. http://www.Amazon.com/s/ref=bl_sr_electronics?_encoding=UTF8&node=172282&field-brandtextbin=TomTom
A Tomtom antenna is an external unit to be used with Tomtom GPS navigational units to give a wider range for your GPS needs.
Yes TomTom does sell mapping software for their GPS units. Most of the new GPS systems come with a cable that you will link to your computer to update the maps and features of your TomTom.
That really depends on what models. Some models, such as the Etrex from Garmin, are more expensive than some of the tomtom units, but in general they are priced about the same.
There are several different kinds of TomTom GPS units. Most of their units will run the average consumer between $90 and $160, depending on what model you choose.
As long as you have the latest maps the TomTom GO 720 should be fine in the country and subburbs
The TomTom and Garmin units tend to be close to the same price and quality but the Garmin is a slightly better deal; you'll get more features.
Tom TOM Gps units use the NAVTEQ GPS maps.
TomTom's population is 3,500.
the two greatest selers of gps units and systems are garmin and tomtom (magellan is also pretty reputable). i prefer using garmin out of the three units.
I would say yes that you probably do need a TomTom receiver with every TomTom GPS, however to be sure i would maybe go to the TomTom's website and see what it says.
TomTom has excellent GPS units that even your grandmother will be able to use.
The TomTom should have a model number on it and when you do buy a screen protector you should be able to look on the box to see if it is compatable with the TomTom that you have.
