Objectives: I was looking for an inexpensive way to display my position on a map screen as I was moving. Most important was to get a non-proprietary solution which included maps. By keeping the GPS function in a separate device from the display, battery life can be optimized. The GPS is left on and logging continuously while moving (17 hours per battery) while the mobile phone is turned on and off as required depending on the length of the trip. Another significant objective was to reduce gadget clutter. This one device contains Phone, Internet, Bluetooth, Data Storage, Camera, Music Player, and Mapping functionality.
