I have an A-210 in my airplane. It works quite well, including the intercom. The intercom is a bit squirrelly to get wired and configured right, but works reliably once done. Mine is connected to a pair of Lightspeed headsets and the audio out from the Dynon and Traffic Watch. The squelch levels have to be set in a configuration menu and are not available to twiddle with in flight. Tx and Rx range are excellent, the dual Rx works great and the display is very easy to read.
