In the USA, the only thing with national coverage is transponders. ADS-B
is available in some parts of the country, but the only general aviation
"solution" is the GDL-90 from Garmin. It's the size of a shoebox, weighs
6 pounds, draws 1.75 amps on 12 volts, and costs $7000 (installation
extra). Makes a transponder seem like free candy.

Another oddity - it quotes the MX20 as its (only?) compatible panel
display/control unit, but look that up on the Garmin website and you'll
find its labeled Obsolete - Discontinued. What do9es that tell us about
the viability of the GDL-90?
