Ok, so im sure you all know that annoying sound when your phone is by a radio.
what i was wondering, is when you are using say an itrip or any other fm transmitter it seems to do it ALOT more than usual without getting any calls or texts.
what im wondering is, instead of putting it into airplane mode, can i just use the services.app and turn off edge?
is it even edge that makes it do it randomly?
because every time in my car id still like to recieve calls.
