I have both and love them. The PCAS is nowhere near a proper TCAS, and has many limitations, but it's still helpful. The Garmin 695 I can't find any fault with at all. It is brilliant!
With the ridiculously expensive interface cable, the two units integrate easily together with power being Y split to both.
I don't yoke mount, but stick the 695 to the side window on the passenger side with a RAM mount. Zaon gets 'dash' mounted with Velcro.
If you want to try them out before you buy, get in touch. I'm based out of Bournemouth.
