Question about Boating
SOURCE: fish finder
You have either the DSM250 or DSM300 digital depth sounder module installed. The C80 is not seeing it.
There is an LED status light on the DSM. For starters, it should be lit either red, yellow or green to confirm it is actually powered on. We are hoping for a green light.
Double-check the cable between DSM and C80 for tightness. Also double-check the DSM's power cable for tightness.
The DSM's are sensitive to voltage level onboard. Make sure the DSM's connections to the circuit breaker panel or battery are tight and clean. Double check with a multimeter the there is 12V DC available to the DSM.
Let me know what you find.

You can find the manual you need at: http://www.humminbird.com/support/FAQ.aspx?faqid=72
It is listed in the legacy products area with the wide series of units.

I finally got an email reply from Navman. If the unit is less than two years old (mine is not) they will repair it. If it is over two years old, or if you can't prove that it is less than two years old, you can ship it to them and they will repair it for the low, low price of 355 US dollars.
Pretty nice of them since it appears these units are highly problematic isn't it? I am wondering if they guarantee their fix, or just have you on the hook for another 355 dollars later.
Good Luck Everyone,

I don't think your old fish finder is the LMS-332C GPS Receiver listed above in the description. You don't need the speed wheel for the fish finder to function just the transducer and transducer mount. You should mount that on the back of the boat towards the center but not too close to the motor and not too close to the side of the board. Don't let it hand below the level of the boat. That should keep it from getting hit by the trailer or dragging on the bottom. Try to make it as level as possible. The green and white wires may be for the speed wheel but i'd need a model number for clarification. Hope this helps.

You can find out which one is serving the device you wish to repair by waving a small spade or wide metal object about a foot from each of the existing transducers and have someone else monitoring the insruments on the concole.
