Well...the fan on front doesn't quit turning if either happens. Regarding the audio panel, it fails over to a straight pass through to whichver radio you have set to #1. The txpdr isn't a big emergency either - most everyone is going to a remote mounted transponder either controlled through the EFIS or the radio, so you're in the same boat either way.
That being said, you're certainly not forced into using remote anything. We do a lot of stacks with GTN's that still have panel mounted txpdr's and audio panels. Note that you can take a regular old Garmin transponder, leave it panel mounted and still control it from the GTN (or EFIS) if you want!
