pack expands the uses for your GPS unit. The PPP makes it easy to transfer your unit from a boat to a car, recreational vehicle, airplane or other vehicle without drilling and mounting a second bracket. You can use your unit in your own car or boat, then take it along when riding in a friend's vehicle that's not equipped with GPS.
Most LEI portable power packs can be used with eight "D" cell alkaline batteries. Some use an optional sealed, rechargeable battery. For in- formation on the PPP for your unit, see the accessory ordering informa- tion inside the back cover of this manual.
