GPS Devices
Map Capabilities
Most GPS models come with internal map capabilities. Manufacturer provides maps with details up to street level in the hard drive. The menu option enables you to access the desired data. Comprehensive street level maps can help you identify the coordinates of the destination on the map by using just the name, or locate the destination on map by giving the coordinates. For some models you will have to subscribe to a plan to update the maps on an annual basis.

Some models provide map information in memory cards having detailed information of a particular region. Thus you will need extra cards if you have to store information for more coverage. Map cartridges are more flexible but can prove to be expensive. Check the few models at: http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=Map+cartridges+%2F+Data+cards
Models which enable one to download the latest maps are also available. Check such models at:

Some brands provide map information in CD-ROM, DVD-ROM discs. Check out one such model at: http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=DVD
Receiver type
There are 24 GPS satellites in six orbits around the earth. GPS receivers track these satellites to compute the information of your location, the bearing, distance and time left to reach destination and other route options. Since there are 12 satellites at a time in view, each of them is tracked continuously to generate the information. Latest GPS receivers marketed today are commonly 12 parallel channel receivers.
