When I bought boat the old Magellan 5000 GPS had been removed but this unit with No. 43-00003-001 on it remained. Does anyone know what it does? Do you think it reduces the voltage? It has two terminal underneath labelled 1 & 2 which someone has scratched - & + respectively. Any ideas? If I put 12 volts in what is likely to come out?
