Raymarine won't do anything anymore... I tried on My 31 before I sold it.... and it was a few years ago.Resurrecting this old thread. I'm now experiencing constant disconnects on my 2008 350. It was an intermittant problem since I bought the boat in 2015, but now it's suddenly much worse. How have others dealt with this issue? Its an old unit, so getting Raymarine to do anything likely not going to happen.
make sure your select transducer is on the transducer your using. The transducer label is usually on the cord plugged into the unit. I had to do this a few times to get it to behave.
