The Technology Inside Navigation Systems For Cars
When you are looking for the best GPS systems features, remember to select the ones that have at least a couple of this features:
- Top view for the map
- Top view for the map with the map rotating with the automobile
- Bird’s eye view for the map or the next curve
- Linear gauge for distance, which is redundant if a rotating map is used
- Numbers for distance
- Schematic pictograms
- Voice prompts (Audible driving directions)
- Text to speech
- Real time traffic updates
- Internet connectivity
You may also want to know that the Road database is a vector map of some area of interest, where street names or numbers and houses numbers are encoded as geographic coordinates so that the user can find some desired destination by street address. The map formats are almost uniformly proprietary, although NAVTEQ are currently trying to address this with S-dal that is a royalty free map format released in the hope that it would become an industry standard for GPS navigation devices.
The LCD screens on some GPS navigation devices can also be used to display television broadcasts or DVD movies. A few navigation systems integrate with mobile phones for hands free talking and sms messaging.
Navigation systems for cars can include personal information management for meeting, which can be combined with traffic and public transport information system.
Other Navigation Systems For Cars Functions
If you thought that navigation devices were only for cars, here we are going to show you some other GPS systems functions.
GPS systems and Golf Carts: Golf Carts may have integrated rangefinders tailored to specific golf courses, providing interactive course maps and live readings of distance measurements to the green.
Advanced car security vehicle tracking systems can relay the vehicle’s location via cellular phone services in case of lost or theft. The technology can also be used to manage fleets vehicle’s, in which case it’s known as automatic vehicle location.
Some systems feature internet connectivity, either via Bluetooth to a mobile phone (in which case the device can typically also be used for hands free calling), or with a built in GSM SIM card. This connectivity can be used for up to date traffic information, to fuel prices, as well as to search for local distances. Such features are included in the Garmin Nuvi 3790T, The Motorola motonav TN765t, and the TomTom XL 340 S.
