How do I change the fuel currency symbol/unit on my Garmin Nuvi 1390 to "$"?
My 4 year old daughter has been playing with my GPS and now the fuel currency symbol is "py6". Anything to do with fuel cost ends with "py6", for example under Fuel Economy it says "Cost of Fuel Used 1.50py6". What I would like it to say is "Cost of Fuel Used $1.50".
