@tamalien and @SANGEKi1985 - Thank you, that was it, I have a Honeycomb Bravo throttle quadrant and buttons 46 and 47 were programmed to turn the Master Avionics on and off. The odd thing is, the keys on the Bravo never caused the same problem with the avionics switches on any other aircraft, only the Cirrus SR22, in other words I am able to activate the avionics with the click of a mouse on the C172, G58 Baron, even commercial airliners.
