Have been playing with intercom and ipod, etc. Can you have external speakers and helmet speakers both on at the same time? I thought I did once, but can't do it now. Also, I finally got the intercom to work without the PTT switch, thanks everyone, but it is really sensitive to wind noise or something because it cuts out frequently. I have the vox set to absolute lowest point. What settings are people using? This is driving me nuits. It seems as it should be simple, but it is very very sensitive evidently.
