I am trying to learn as much as I can on my GPS Map 498. The GPS came with the boat I purchased last summer and works great when installed on boat and powered via DC. When I winterized I brought GPS in house to learn more through the simulation mode BUT it will not even turn on via the instructions from the manual. Is there an internal battery?....Am I missing something as to why it won't power on?....
