Question about Navman Trackfish 6600 GPS Receiver
Usually blackening of a part of screen is most probably due to faulty LCD screen.
he Display of a GPS Consists of (2) Separate Devices that Work Together.
# The Liquid Crystal Display (LCD)
# The Touchscreen with Glass
The touchscreen consists of several transparent layers with spacers that are applied with an adhesive to a thin pane of glass. The touchscreen & glass lies on top of the LCD display. The touchscreen & LCD display both have their own flex cables that connect to the main board.
The touch screen has a ribbon flex cable with 4 or more conductors, each conductor representing a direction such as:
1. X-Coordinate, Left
2. X-Coordinate, Right
3. Y-Coordinate, Up
4. Y-Coordinate, Down
Most GPS units use a resistive, analog touchscreen. A voltage is applied to the touchscreen and by pressing anywhere on the touchscreen, it acts like a voltage divider, returning a specific voltage value, based upon the location touched on the screen. The GPS is programmed to read this voltage and it translates it back to a specific position on the screen, which may or may not activate a function.
The touchscreen doesn't have to sit directly on top of the display. If you were able to set it beside the display, you could still press the touchscreen and activate a function. The LCD display has no idea where the touchscreen is mounted, all it is concerned about, is what area is being pressed and whether or not that location matches a particular function on the LCD display menu.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Yes, it is possible to download the coordinates from navman to your desktop. connect your GPS to your system via the USB cable that came with the GPS and wait for your system to detect it, once it detects it, open the files and download the information to the desktop.
