There are two wires between the lump and the earbud. One is copper colored the other is green. Could I just splice those two wires to the Giro wire between the helmet connection and the mic lump... and be able to receive transmissions through the helmet speakers? Then just use the cobra 'lump' microphone and button to transmit?
I'm not sure about the impedance of the earbud or giro speakers, but I could
hear the radio in the helmet speakers when I plugged the Giro jack into the radio. I just could not transmit with either the mic button or the radio itself.
I have also tried Motorola, Midland and Uniden radios....all with the same result. I could hear but not talk. (with the Uniden radio, the Giro jack has to be pulled out one click after being fuly inserted, in order to hear sound)
Geez, you'd think Giro would make these things more compatible with radios. Who the hell wants to use a cell phone on the mountain? I don't think I've had much luck getting any reception up North. I will call Giro tomorrow and see what they have to say about it. But in the meantime, it seems like you may be just the person who can help me, sjjohnston.
