device is. One way to determine this is by how many channels the GPS unit has. This is
because more channels means the unit will be able to communicate with a larger number of
satellites, resulting in more coverage. Another way to determine the accuracy of most
automotive GPS units is through how its antenna is designed. Make sure the antenna is placed
in an area of the unit where it will be able to stand freely.
The next thing to think about when looking at automotive GPS units is size. There are some
automotive GPS units that will not be portable. Onstar, which has to be installed in one’s
car, is an example of an automotive GPS unit that can not be moved from car-to-car. Many
other automotive GPS units vary in portability.
Thirdly, perspective buyers of automotive GPS units should take notice of a unit’s
interface. More expensive automotive GPS units will contain voice-activation and/or
touch-screens, while cheaper ones can only be used through a series of buttons. If another
person is in the car, using buttons is not as bad, but if only the driver can use the unit,
it is important that it be as hands-free as possible. It is also important to try to get an
automotive GPS unit that has the capability to give directions through a computer-generated
voice. Doing so is another way to ensure that the driver of the car keeps their eyes on the
road and nowhere else.
The software that the automotive automotive GPS unit uses is also critical. Most top of the
line units have very good mapping software included with the unit. However, as time passes
the mapping software becomes out of date. You should make sure that you automotive GPS units
software is updated at least once every 6 months. Frequently there is cost for this service
but if you live in fast growing urban environment then it is a good investment. Your
automotive GPS unit is only as good as its operating and mapping software.
