Narrative:

During climbout and after establishing initial contact with approach; I had made two more replies to their queries (identify; and radar contact). While performing my cockpit duties there was a momentary break in radio chatter. Upon immediate investigation; I realized that the frequency box on the garmin gtn 650 had 'flip-flopped' back to CTAF (122.7). I immediately switched the frequency back and heard the last three alpha/numeric identifiers of my call sign. I answered this call and was handed off to the next successive controller for the route. Prior to the loss of communications I had isolated the crew from the passengers on the audio panel mounted above the garmin gtn 650. It could have been at this point that I may have inadvertently touched the 'touch screen' of the gtn 650 which could have 'flip-flopped' the frequency.
