For a long time I was looking for some GPS.
Moto series from Garmin were too expensive, but i still have my old MIO PDA with Chinese Map.
Problem with PDA was that someone have to navigate me, or if I go alone I have to stop way too often and confirm that I`m on the good road.
Surfing the net I found some sort of solution. I believe cheapest possible.
Simple food container, like we use to keep in fridge. Sponge as anti-shock protection and plastic foil as water-tight cover.
