I need a manual for Navman trackfish 6600

Hi Gil!
Easy peasy.
From your 6600, the data sends are the white wire NMEA (+) and the black wire (-). There are two black wires. Doesn't matter which one you use as they're interconnected anyway.
To your UM425, the green wire is NMEA in and the bare wire is ground.
So...
white from 6600 to green and
black from 6600 to bare.

Hope this helps you out.

The closest I could find was for the Navman 6000/6500 models.
See the link below.
Hopefully it'll be of some assistance.

Try a factory reset - that worked for me when my Northstar Explorer 660 stopped by itself again and again. You find this reset commando by pressing MENU twice and then under Systems menu, if I remember it correctly. There is also a RAM Clear commando. This is done by holding the MENU button pressed when the GPS is switched off. Keep it pressed while switchin on the GPS, still holding the button pressed until the RAM Clear menu appears. You will probably loose all waypoints etc. by doing this so try Factory Reset as your first alternative. Good Luck! // Jonas, Sweden
