F1 GTN 750 and Nav1 Audio

[tjrush 54]

Just updated the F1 GTN750.  Now as soon as the GTN goes active the nav1 audio button on the audio panel lights up and the morse code begins.  The problem is that I can't turn it off.  If I click the button it goes off but immediately comes back on. I had  this probl;em the last time I updated the GTN.  I don't remember how I fixed it. 

Again this problem is only wiith aircraft where the GTN is installed. Anybody have any ideas??
