Can anyone help please? I recently bought a boat and the GPS is a lowrance lms332. I am having a problem with it popping up a message saying that the unit is not responding. Does anyone why I am getting this message? It doesnt do this all the time just sometimes so it tells me it must be the wiring right? When I first had the GPS the chart had water depths all over the map I downloaded a update from lowrance and put in my system now the water depths are not on the chart?? Can anyone help a rookie out? Is there any way to download a better chart?

Thanks for any help
