right appears. Now press the MENU key. Select “INITIALIZE GPS”. A screen similar to the one below right appears. Use the ar- row keys to move the crosshairs to your approximate location on the map. You can use the ZIN and ZOUT keys to enlarge the map which makes it easier and faster to find your location. The box at the bottom of the screen shows the latitude and longitude of the cursor position. A box pops up on the screen, showing the name of the nearest highway (if a MMC with a map is installed) along with the distance and bearing from the last known position. Once you have the crosshairs on your lo- cation, press the ENT key. The unit returns to the satellite status screen.
Using this manual initialization method loads a position that’s close to yours into the GPS receiver. It should now have position, time, and date, thereby giving it the data it needs to determine which satellites are in view. Once the satellites are known, the receiver searches for only those satellites, making a lock faster than an auto search method.
All position and navigation data flashes until the unit acquires a position. Do not rely on any data that is flashing! When the numbers are flashing, they represent the last known values when the unit lost it’s lock on the satellites.
Position Aquisition
When the receiver locks onto the satellites and calculates a position, it shows the message “Position Acquired” on the screen. Once the unit has acquired the satellites and the position acquired message appears, it’s ready for use.
(Note: The altitude data may still flash even if the unit shows a “Position Acquired” message and all other data is not flashing. The unit must be locked onto at least four satellites to determine altitude. It only takes three satellites to determine position. You can navigate with this unit if the alti
