Vehicle Global Positioning Systems
A GPS unit for your vehicle comes in very handy if you find it difficult to read maps or just ask for directions. Portable vehicle GPS units display the intended route as you travel, give spoken directions and will plot a route before you even leave. No toll roads, fastest time and shortest distance are some of the things you can choose for your routing preferences.
Look for an vehicle GPS unit with the most memory. You don't want to be loading maps into the device while traveling to a destination.
A really nice feature of most portable vehicle GPS units is the ability to display points of interest such as gas stations, banks, tourist attractions and hotels. You can also specify a particular point of interest and have the unit plot a course for you. Once you've pin pointed a spot where you want to go, a portable vehicle GPS device can calculate a route to that exact spot. The higher end GPS units allow you to call a number displayed on your GPS device or even access phone numbers through a wireless, bluetooth compatible transmitter. If you're willing to pay a subscription, you can get local weather reports and local traffic through a premium service.
Vehicle Navigation
The nüvi 2x5 models all have the slim layout that
Garmin introduced with the 200-series a while ago, so they all sit easily in your purse or pocket, and a rechargeable lithium-ion battery that makes them easy for navigation by car or foot. All of the units include helpful travel tools like a meanurement converter, JPEG photo viewer, world travel clock with time zones, calculator and currency converter.
The nüvi 780 has the very-bright, 4.3-inch (diagonal) touchscreen LCD gives is anti-glare for good of viewing throughout the day and quickly changes its color profile for great viewing at night or in low light. It has 2d or 3D perspective views.
The widescreen display gives you 70% more usuable screen area than a 3.5-inch LCD. Usually this translates into a superior view of the area through which you are driving. This is very useful in displaying what parks, other restaurants, ATMs, cheap gas stations, etc. are nearby, or in letting you know whether an annoying detour is a lousy idea. Also, the unit itself is bigger, meaning buttons on the screen are more widely apart and pretty much easier to push.
The
TomTom GO 720 is full of features, such as an easy tip feature, a customizable quick status bar, an extensive and easy guided tour, and even a 'Help me!' display, so it guides you through its easy usage as much as to your chosen destination. It also has a personalized an easy to use shortcut menu, 'current location icon or button' options, and plenty of POIs (points of interest) so you can discover what you want wherever you are like a old timer local was riding with you. Taking this type of navigation beyond just ease of use, the 720 lets you play your popular music wirelessly over your own vehicle's stereo system via its built-in and easy to use MP3 player and FM transmitter. Now you can get into your music on the 720, all while easily providing acurate navigation instructions and still working with your hands-free telephone calls. This really cool navigation device even includes a document viewer and a clear photo viewer, so you can take your work with you or quickly download and enjoy your own holiday photos wherever you are.

The snappy user interface makes the
Magellan Maestro series very easy to use. Use the huge icons on the 4.3-inch widescreen touch screen to look for your destination by intersection, address, or any of 6 million points of interest (POIs), including good restaurants, fine hotels, busy airports, cheap gas stations, and more. You can even use an onscreen icon for a nearby destination, see name and address, and get an instant route. Turn by turn visual and spoken directions guide you every step of the way.
With a huge, 7" LCD display and accurate traffic info, specific weather and cool entertainment features, the Garmin 7500 is the best tool for all your far away travels. Plus, the 7500 has dead reckoning, highly accurate technology that makes it extremely good in all conditions. Garmin has made the unit specifically for bigger cars such as RVs, semi-trucks, and buses, and it offers excellent features for those who have lots of time on the road.

It even announces the name of exits and streets so you never have to take your eyes off the road. In addition, the 7500 accepts custom points of interest (POIs), such as school zones and safety cameras, and lets you set proximity alerts to warn you of upcoming POIs.
