Installation Notes
11. Upon completion of Copying program to RAM, the software
bootloader will burn the program to flash.
12. Upon completion of Burning program to flash, the MX 500 will
jump to the program itself (POS2 screen), and software up-
grade procedure is completed.
13. If there's any problem, please go back to step 1 and try again.
Hint:
It is highly recommended that the MX500 navigator be cold started
after downloading the program. Please note that all settings
including waypoints and routes will be lost.
This is important to flush out the residual memory, which may cause
problems with the operation of the unit.
Memory Clear Procedure:
1. After downloading the software, turn the power off to the MX500
by turning off the 12 VDC circuit breaker (this may also be
accomplished by removing the 12-Pin Cable from the back of the
unit).
2. Press and hold down the CLR key.
3. Apply 12-volt power to the unit and wait for about 5 seconds.
The MX500 will come on and display the Northstar logo.
4. Release the CLR key.
5. The memory is now cleared.
