Vehicle GPS Units - Which Features to Look For When Buying a GPS

Do you ever end up driving round a place you've never been before and getting yourself utterly lost? Yeah, me too, until I got myself a car GPS unit. Deciding which model to get can be confusing though, but that's why I have written this article.

Main Car Sat Nav Unit Features

There are standard features which virtually all modern sat navs will have, and without which, the system would be almost useless. These include:

Touchscreen: You need to be able to quickly select your options, and an easy-to-use touch screen is the best way to do this.

Route Maps: If your new GPS unit doesn’t know the area where you live, it would be rather useless woudn't it?

Audio Directions: You can't keep stopping and looking at where the Sat nav system says you should go, you need to be told out loud, “turn right”, “turn left”, etc.

Additional Automobile GPS Navigation System Features

As well as the standard Sat nav features talked about above, there are some extra features you may want to look out for, for example:

POI: Sometimes road directions just aren't enough; you also want to know where the interesting sights are. For instance, if you’re on vacation in a particular area that you’ve never been to before, you’ll want to know the various important historical monuments, or you may just want to know where the best entertainment venues are.

Hands-free Calling: Using a phone while driving is dangerous. Several GPS system can connect to your phone, giving you hands-free access.

Lane Assistance: Several GPS units these days have the ability to give you detailed help with navigating the lanes of busy roads. This way, you'll never take the wrong exit.
