I have a 958cdi hd on my bow. Unit is about 3 months old, it came rigged from the factory. I am having issues with my readouts. On the menu, I have depth selected in the top window, temp. selected in the second window, and time selected in the 3rd window, with the remaining windows in the off position. The windows have a total mind of their own. One minute ill look down and Im showing gps coordinates where the time should be, voltage where the temp should be, etc. If I go into the menu and try to fix it, sometimes it does and sometimes they wont change even as I am scrolling through the selections. When it does fix it, its only temporary. This has become really annoying on tournament days, especially not being able to glance down at the time as 3:00 gets close. Anybody else had this issue and is there an easy fix or will it have to be sent off to Humminbird?
