I wonder how many installs do switch automatically. I think a very small % does.
Mine does.
Mine too.
Here's an idea for a perfect GA business model: set up a really good avionics shop on Losinj (LDLO) or Brac (LDSB).
Or Zadar ... get an ILS there and enough concrete to depart a Tupolev on one engine 
It would actually be OK for the Germans. They can pop down there easily, and you could offer a free fuel tank top-off and free landing fees and you would still be well below the price quoted by the well known German avionics shop - the one which recently quoted a friend of mine €1000 for a single KMD550 data cartridge.
The need to cross the Alps would also filter out the quality customers - only kidding, honestly
