I just purchased a new Scala G4 kit and absolutely love it! I read up on them on a number of forums and reviews online and had heard issues with connectivity, but I had none. I bought the kit for just under $200 and can say some of the best money I've spent: [URL="http://www.sumofallparts.net/Scala-Rider-CARDO-G4-HEADSET-p/tr21-0075.htm"]Kit[/URL]
I highly recommend this kit to anyone looking to get an intercom system. I bought this so a friend and I could communicate on a trip we have planned next month and realized it is much more versatile than that. Connected my iphone to it no problem, ok it took a little while to figure it out, let's just say it helps to read the manual. We went out for a short ride and everything works great, I only had to adjust my speakers once and the sound was awesome. It even fits both of my helmets, I have a Shark RSI and a Suomy Spec1.
