I was going to start a post today on the Garmin 240 Blue, as I installed one and used it for the first time yesterday and had problems. I'll just ask on this thread.

First, it was intermittanlty powering off. I am sure that all my connections are solid all the way to the battery, cant figure out what the problem is there? any ideas?

Second, when it did stay on, it would not give me an accurate reading of the depth. It read 500-650 feet all day long even though I know I was in 75-200 ft of water. At some times, the depth readout would slightly fade and return, fade and return, as if it was trying to tell me something.

Speed and Temp work fine. Voltage was +15v.

Anyone know what the heck the problems might be? AkKings, I know you know alot about these, any ideas?
