Gave a friend of mine an old GPS that needed a battery and updating. Was less expensive for me just to buy a new one with lifetime updates. Anyway the reason I gave it to him was so he could use it as a speedometer in his hot rod. Still worked on 12 volts and having old maps didn't matter.
Maybe someone has an old GPS laying around to donate to the cause..
