In the past, I paired with one guy and it was fine. But I want to be able to pair with at least 4 in an open channel, so I was pleased to hear about v4.0 allowing this. I just upgraded a couple days ago. I paired with my new Garmin 220 GPS and it worked great. But I would like to know in advance about other issues. 2 friends went in on a pair and I suspect I will have to upgrade the firmware on them.
Are there any wacky things going on? I heard of volume loss in 4.0, that would be bad as on the highway, I need all the volume I can get.
