I asked this question a couple years ago. someone told me about a different web site and a different GPS. I'm wondering if anyone know if TomTom has progressed any and or partnered with Google maps
just found this but not sure if it's true or what models it works with

guess I spent about an hour on this, turns out the send to gpd button in google only send the destination not the actual route. duh I can type a destination on the device ... gawd
edit - turns out the gps has a bicycle feature which I used in conjunction with handwritten notes. worked out fine. after 1 more ride I should have the route down and no longer need the gps.
