The 705 uses the same City Navigator software as Garmin's in-car and handheld units. I've used all three types over the years with many different versions of City Select/City Nav, and as far as I can tell, the Edge 705 performs nearly identically. You can tell it your vehicle type (car, bike, RV, etc.), and it will avoid routing you onto unsuitable roads, such as major roadways in the case of the bicycle option. It also has the "Go Home" routing option that you mentioned, though its buried several menu levels deep.
