GUYS .... let's not get the Elite 5DSI & the HD's capabilities confused. Bill's question is whether or not the E5DSI unit can backtrack to a point on the screen history, that's more than a minute or two old. Simulator/emulator programs won't answer that question, since they're preprogrammed "scripts". What Bill needs to know (& us other E5DSI owners, also) can only be answered by live testing this unit on the water. (or Jason's expertise/knowledge)
