Navman 5500 does not support C-MAP MAX maps.. only C-MAP NT+ maps.

Apparently it is the internal battery that might be at fault or just be old. I'm going to replace mine as it costs a fortune to get Navman to do it. Can't find any info on how to do it, but should be simple. Only thing is that you lose all waypoints and other user input data (unless you have the PC Planner from C-Map).

Yes the screen is replaceable, there are four screws holding it to the PCB and a short ribon and a two wire power lead.

1.The TRACKER is designed to operate on a 12/24 volt battery system, where the voltage may vary from 10.5 to 32 volts. If an excessive voltage is supplied, a fuse will be tripped, turning the display unit off. Check the fuse.

2. Check that the power cable connector at the back of the display unit is securely plugged in and the collar is locked in place. The collar must be secure for watertight connection.

3. Measure the battery voltage while the battery is under load - turn on some lights, radio or other electrical equipment connected to the battery. If the voltage is less than 10 volts:

- the battery terminals or wiring on the terminals may be corroded.

- the battery may not be charging correctly or may need replacing.

4. Inspect the power cable from end to end for damage such as cuts, breaks, squashed or trapped sections.

5. Ensure that the red wire is connected to the positive battery terminal and the black wire to the negative battery terminal. If wired for the Auto Power option, ensure the yellow wire is connected to the ignition circuit. Also check the boat's main switch circuit

6.Check for corrosion on the power cable connector and clean or replace if required.

7. Check fuses that are placed in line with the power cable. A fuse can be blown despite appearing to be good or the fuse may be corroded. Test the fuse or replace it with a fuse known to be good.
