Hi guys, hope someone can help me here. I bought the boat with the above fish finder, GPS. The problem is the unit reboots itself every now and then. It is soooo frustrating especially when you are going according to your previous route on the GPS. I have checked the fuse, I have checked the connectors at the back of the unit and all seems fine. Is this a common problem on them? What else can be wrong? At this stage I feel like fixing the problem with a big hammer.
