Its water ingress causing a short in the high voltage wiring PCB.

Open the unit with a 1.5mm allen key, unscrew the power/data cable sockets with a spanner and GPS antenna inlet with an 8mm socket (NA to i models) .

Where water has arced there will be burning black on the green PCB evident, cut the PCB wire and remove the section around the burn.
solder a new wire to bypass the short.
Dry the unit and seal with silicone to prevent re occurrence.

Its a 2 hour repair requiring a high DIY soldering standard but off set it against the time it will take to reload you waypoints in a new plotter , its well worth the trouble.

Navman Tracker 5500


I am having same trouble. I contacted Navman NSW and went through all the settings without result. It was suggested that the problem could be the external antenna, if not a fault in the machine. I have seen an after market antenna for about $19 so I might try that. It does seem as though the antenna is not talking to the Tracker.

Hitachi 50V710 The picture is dim, then the bulb went out. I replaced the bulb. all works but the picture is still dim. You can barely see the screen durring the day. And can only use it in a dark room...


I've seen this in two scenarios.


First: The housing of the bulb is dirty (the lens the bulb lights onto) and the internal screen is dirty also.


The second: The bulb is wired reversely of the proper way to wire it. This will light the bulb, but will not light as bright as when it is wired correctly!


Thank you and please rate!

I had similar problem and I opened up and replaced the L-shape (usually) back light that I got from other wreck, where the DVD reading lens was not working but the backlight was working. Usually it is not that fairly easy to check any loose wire, bcos there would not be much loose wires. Try, you may be lucky.
