I have a basic garmin device (its a nuvi, but about 5 years old), which I use in the mog. I havent got a power socket either (on my to do list) when the unit is fully charged I can do a 3 hour trip comfortably, so long as I turn it off when I don't need a direction immediately.
I did have a solar charger gubbins (solar monkey, I think) which would run the sat nav for about another 45-60 mins if it was sunny. But some scrote stole it from my car whilst parked up outside halfords in Telford for a few mins (it was in a nice black case and probably looked like a wallet of CD's)
