I'm running StreetTalk. I can tell if the BT 338 is on because, when it is on and I activate GPS in StreetTalk, I only hear one or two tones, and then StreetTalk tells me GPS is active. If I hear more than one or two tones, I hold the button down for a second and then, when the BT 338 is on, I hear StreetTalk tell me that GPS is active.
