Tips & Warnings
Crossover handheld GPS units that have a large enough screen for car navigation can typically be mounted on your car's dash. Mounting accessories are usually sold separately, however.
Upload detailed maps of areas where you will be traveling. Handheld GPS units come with pre-programmed maps, but more detail can be useful to navigation.
Carry extra batteries with your device so that you aren't stranded without navigational assistance.
Don't go out into an unfamiliar area relying solely on your GPS device for navigation. Something could happen to your unit or it could malfunction, and you could be lost. Always bring a paper map and compass with you just in case.
