GPS Device Selection Guide
Posted: Wed Oct 24, 2012 7:02 pm
There are lots of GPS devices on the market and many are confused, which is the right device. To choose the right device, the potential buyer has to take into the consideration the purpose of future usage. As we are here talking off-road, I will concentrate mostly on GPS devices to be used off-road.
Physical
Screen size and type
A minimum should be 10 cm in diagonal, sunlight readable screen, so you can see all the details comfortably from your seat, behind the steering wheel, with minimal resolution 272 x 480 pixels. Touch screen option is preferable and convenient to use. However the device should give you an option to resize the icons on screen to be able to hit them when needed.
Water and Dust Proof
The device must be protected against humidity and dust, as we are driving in certain not very comfortable conditions. IPX7 is standard which should be taken into consideration (no ingress of dust, up to 1 m of submersion in water for 30 minutes).
Battery Life
Up to 16 hours, if the charging cable can get broken. The car charger option is a must.
Memory
The device must be capable to use any commercially available memory card, to add storing capability on the top of internal storage.
Features
Waypoints
Able to store waypoints at any moment, with additional text information, minimum 1,000.
Tracks
Able to store driven tracks and display them for the later use, minimum 200, where each track should be able to score 1,000 points as minimum. Many devices are adding points to tracks based on turns or straight driven distance.
Routes
Ability to store routes created outside the device (on computer), minimum 200. Routes are straight lines between waypoints and are not copying terrain turns.
Maps
Ability to install current area maps, showing roads and marked off-road roads, with other points, like fuel stations or rescue places.
Connection to Computer
Ability to retrieve and store data from device to computer and also from computer to store cleaned data on the device.
Ability to upgrade device BIOS as manufacturer is releasing models to the market with full of bugs, and during the updates, they are adding forgotten features or improvements, based on the comments from users.
Navigation
Ability to display the saved route or track on a screen and see or hear to the navigational voice commands. This feature can be on-road by voice or off-road by displayed messages.
Ability to be instructed on-road by a voice commands at junctions, to be able to navigate from point A to point B.
