Question about Garmin Gsd 21 Sounder Blackbox Fishfinder Module
When i put the sounder on the whole screen is filled with interference
My gsd 21 does not work with my gps 2106

Interference like that is usually caused by electrical noise. Does it happen when everything else on the boat is turned off? If the answer is no, then you can isolate the source of the interference by turning things on one at time. Follow your transducer cable and make sure it has not been damaged or altered in any way.
Also make sure that your gain is set to auto
The GSD 21 has an LED indicator light on it. If it detects a malfunction the LED will flash in distinct colors or patterns. In the troubleshooting section of the owners manual there is a list that explains what each flash pattern means.
