What about supporting (with appropriate devices) the Garmin SL-40 protocol, which is able to set frequency/memory of the radio getting the data form the GPS system?

I‌'ve tested this feature on seeral different acft, and I think it is an extremely interesting feature: one time you get acquainted to it, it's hard to come back to setup frequencies by hand (and sometimes also setting the wrong ones...)

N‌ot only Garmin system does support this feature: for example the Trig radios (made in UK...) may be driven  ‌‌‌in such way.

W‌hat do you think about?

R‌egards,

Today, I installed XCSoar on my tablet, because I think controlling of the radio via tablet is very convinient.
