Or you can get free maps, thus one of the first thing I did was download to the 810 the free North American Open Street Map set, onto the unit SD card. DC Rainmaker has good instructions how to do this.

In essence and as I understand it, what's being created in Connect is GPS location points and those get loaded to the device, which then overlays the points onto whatever map set you choose to use on the device. It works well.

Thus while the course created on a computer using Connect and while viewing on Google Maps, gets shown on the device on the OSM maps. It still routes into a bike path just fine, so go figure.

You can as well create courses using RideWithGPS which can be downloaded to a device. It does this with a cable connection of device to unit, as opposed to the BT transfer with courses from Connect. It's slower to have to do a physical connection of the device, for me at least, thus I like the BT and have gotten good at using course craation on Connect.
