I figured i would reload v5.1 because i know the new coil is only V5. When i do the update it asks if my old coil is on charge and then goes right to headphones. I had my buddies coil number in at one time and it would ask if his number was on charge, i said skip. This coil works, i have been using it but it seems odd the update does not ask for it to be on charge....like it is not there?
