NAVMAN 6600 GPS/FISHFINDER

[ishhifay]

G'day fellow fishraiders,

I was wondering if anyone can help me PLEASE!!

I have a Navman 6600 gps/fishfinder which has been working beutifal until yesterday.

The gps part is working fine but the sonar part has a mind of its own.

The screen scrolls along in red backround not providing me with the depth, structure or activity.

The transducer still ticks like it should but still no sonar activity reporting to the head unit.

I have contacted Northstar/Navman to tell me they no longer fix these units and have been bought out by lowrance.

I dont mind a lowrance unit but the thing is i have a Navman fuel flow installed, Navman VHF which is intergrated with the GPS unit and all my lifes fishing history spots and so on with me beloved unitwhich makes it hard to part with.

If there is anyone out there who can help me fix this I would really appreciate it.

Sam
