I've been watching this. I had the V-10 and it went south on the flight down to the Desert Fox Fly-in. Unlike Steve, I couldn't transmit. The receiver worked fine. I could hear the click, but no noise out and the transmit icon on the radio didn't indicate transmit.
Long story - I sent the radio back for repairs using the approved procedure. After a week or two, I called to see if they received the radio - they did. Repairs would take about three weeks. I called after about a month and was told that it would be a couple more weeks. I called again and they offered me a new radio to replace the old one. That was fine. After another couple of weeks, I called again and they offered me a V-6 to replace the V-10. 2-1/4" vs. 3-1/8 mounting hole and different wiring harness but I went with that. It came in just a few days. The kicker was the knobs for tuning and volume on the V-6. I am an old guy and much prefer turning knobs rather than trying to remember which buttons to push.
Another thing. A friend with the V-6 complained that his was "too sensitive". He has the V-6 in one airplane and a Flightline FL-760 in his other. He says the FL-760 is much more understandable. Checking mine out on transmit, the mic gain from the factory was set way too high resulting in garbled transmission. As I recall, I reset it to minus 7 or 8 and the transmission cleared right up. I suggested he check the mic gain on his. The V-6 has lots of adjustments to fine tune performance and I like it. All in all not a bad experience - I'd do it again.
