I was mistaken....it is a CP136, not 135M....sorry. The differences are minimal except the M has a built in marker beacon receiver whereas the 136 has the lights but requires a remote receiver.

The 136 apparently has provision to monitor a 2nd comm based on what I am reading online (see Bennett avionics description). It includes the tray and wire plug (harness plug?)

Again...sorry for the wrong description.
