Reviving an oldish thread here but I need a clarification relative to multiple bikes and GSC units.

Once you have detected and set the Edge 500 head unit with the GSC10 for Bike1, Bike2, etc. does the unit remember each specific GSC as long as you select the correct bike when you start a ride? Or do you need to "reconnect" the head unit and GSC each time you change bikes. I am assuming that each GSC unit has a unique signature that, once detected, is remembered for each bike you are using. Is this correct?
