So how does that work? Do you reset the odometer on the Garmin to zero when you fuel up the car, then punch in the amount of gas you put in the next time?

As I don't run my GPS all the time, it is a useless function for me. And considering that you can easily computer your MPG when you fill up your tank by dividing the number of miles driven by the gallons of gas you put in to fill it up again, it is easy to do manually. I keep a log in my Palm Pilot, and if by chance I don't have it with me I simply get a receipt and note how many miles I got out of the tank.
