I fitted one a few weeks ago to replace an old VAL 760 TSO.
I got the pre-wired harness with it from Aircraft Spruce that really simplified the installation. They didn't make the P2 headphone wiring long enough to reach the back seat, but other than that it worked well.
So far, I'm very impressed. The stand-by frequency monitoring is useful, the intercom works very well. I have one of the aux inputs connected to a Garmin 795, but it could also be used for music input and is muted when tx/rx is in use.
It must be the best value on the market for a single com installation.
