GPS systems can be distracting - especially for new users. Images change and catch the eye, options need to be selected, voices come from nowhere. That is distracting. Period. It might save time, but it is important that people remain diligent when using these devices. Safety first, right! The device shouldn’t be programmed by the driver when the vehicle is in motion. Ever. It should be mounted out of the way of the windshield or windows, but not too low that the driver has to divert their attention from the road for more than a moment. The volume should be loud enough to be heard, but not so much that it startles the driver after long periods of inactivity. The map should only be referred to occasionally while the voice directions remain the primary navigational tool.
The benefits of the GPS, if used wisely, are great. Especially for those who haven’t been endowed the gift of the inner compass. As GPS directions become more accurate and foolproof, and as developers learn tricks to help drivers use the software to greater effect, more users drive straight to their destination. Businesses like hotels and restaurants are located for the weary traveler. OnStar uses even uses these systems to help drivers in emergency situations. Next maybe it will tell you where the best pizza can be found - and be correct!
If you want to do price comparisons about different global positioning devices, Consumer Reports has quite a significant section describing the different makes with myriad features and options. An [American] friend of mine thoroughly enjoys the dialect option of her device - I think she has a secret crush on the dulcet tones of the man who pronounces things not only with an Australian dialect, but using the vernacular from Down Under as well.
The most important thing to keep in mind, however, is that the driver should never be programming the device while the car is moving. Looking away from the road for even a second is always something to avoid.
