hey gang, recently, I picked up one of the inexpensive units from a fellow inmate. It is labelled as FodSports. He is Canadian, so the unit is set for km instead of miles. The maps are worthy enough for my limited needs, but I'd like to change the units to miles. Can't seem to do it through the user interface within the device, and I've never messed with updating files using the laptop. Don't even know where to start... I'm only out a few bucks, and plan to upgrade someday, but if this can be made a little more convenient, it'd be nice. I did spend lots of time searching the web, but wasn't able to come up with anything useful. Probably not asking the right questions... Thanks!
