It can be a little tricky when you’re trying to choose a GPS device. So many of them have so many features, they make smartphones look anemic when they’re used as GPS units. Smartphones can be useful as GPS units even when you’re driving your car, but depending on which unit you buy, a dedicated GPS device can give you more of the specific features that will cut down your frustration and save you gas and time. TomTom is known for being one of the top brands of GPS units, so you should be safe choosing pretty much any TomTom. However, you still need to know which specific TomTom model to get. Each TomTom GPS belongs to a specific family of devices, and the series numbers can be confusing if this will be your first time buying one of the TomTom GPS Navigators that are available. Below is a brief overview of two popular TomTom series. It can help you choose the right device without spending more than you should.

TomTom VIA Series

The most recent additions to TomTom’s GPS units are the members of the TomTom VIA series. Because they’ll give you additional features without costing a whole lot more, TomTom VIA GPS units should be considered before the older XL and XXL units, even if you see some good deals on those earlier models. For one thing, every TomTom VIA GPS has Advanced Lane Guidance that directs you to the highway lane you need in order to safely take your planned exit. They also have TomTom’s Eco Route feature. This particular feature will plot the route that lets you reach your destination while using the least amount of fuel. Naturally, the IQ Routes feature is still available if your goal is reaching your destination as quickly as possible.

VIA models come in 4.3-inch and 5-inch flavors and you can tell just by looking at the 2nd digit. If you want to get a nice budget device and don’t mind the 4.3-inch display, consider getting the TomTom VIA 1505TM because it has lifetime map updates that ensure you have the latest map content along with lifetime traffic updates so your planned routes will never have any sudden traffic interruptions.

TomTom GO Series

The TomTom GO series include all of the high-end models although you can find some affordable ones too like the TomTom GO 2435TM. However, you need to be a bit careful when comparing this device with something that has very similar features like the TomTom VIA 1435TM. In fact the specifications look almost identical. The main difference here is the touchscreen as the 2435TM model uses a glass capacitive touchscreen which allows multitouch gestures. This is good if you often check out the map.

If you don’t need this enhanced touchscreen, going for the TomTom VIA 1435TM will save you some money. Both units have voice recognition and are able to understand multiple commands. If you’re willing to buy a GPS unit that costs more than $250, you’ll be able to get a TomTom GO unit that has LIVE features. Then, you’ll get current fuel prices, weather reports and other real-time information.
