How Garmin Calculates Fastest Route


Can someone tell me how the Garmin C330 determines the fastest route? I am curious. Thanks.

It's a fairly complicated formula

Involved in the calculations are the types of streets, roads, highways, etc. that are between you & your destination, and your avoidance choices. My guess is that each road is given a value based on the maximum speed, where it's located (ie: rural area vs. suburb vs city), and it goes on from there.
