All Routes GPX format

Each route has TWO GPX file versions-
1. A "Standard" version with Way and Via points for Garmin zumo 660, 450, 550 and earlier models, other GPS brands.
2. A "Trip Planner" version designated by a "TP" suffix at the end of the file name. This version uses mostly shaping points for compatibility with Garmin zumo XT, 390 series, 590 series, as well as BMW Nav5 and Nav6. Be sure to use the TP version if you have one of these models or any Garmin GPS that uses the Trip Planner App on the device to access routes. "TP" versions usually work best with TomTOM and phone apps as well.
