What are the uses for a handheld GPS?
Handheld GPS units are used mostly for hiking and hiking-related activities such as hunting and geocaching. They can be adapted easily for automotive, bicycle, or marine use with optional mounting kits.
Handhelds receive signals reasonably well in cars, but they don't work well for a major function of automobile GPS - driving directions. Unless there is a passenger to navigate, it would be unsafe to for the driver to rely on the handheld GPS, as it has no voice guidance.
