So does your GNS530 get really hot ?

You may want to ask your avionics tech to investigate this to see if there
is anything that can be done to reduce the heat. Last year I discovered
my Garmin transponder, a GTX330, was getting too hot to touch and I
mentioned this to a local shop tech.

They took a look behind the glare shield and discovered that my avionics
cooling fan had one more available port so the hooked up a hose from the
fan to the transponder. In doing so, they were able to significantly
reduced the heat thrown off by the unit.
