The USB port is above your right leg, pointing down, on the underside of the panel.
This is a USB port wired from the big pin connector into the Skyview D1000 EFIS box.
You should leave a USB stick connected all the time, One has to be connected to take
instantaneous shots of the screen. After a flight, you can also download your flight
logs onto it as well.
I did not like a USB stick pointing straight down under the panel. (Get a very short one if you intend to use that port!) The back side of the Skyview also has a couple of unused (in the RV12) USB ports. So I got a short USB extender cable (male to female), plugged it into one of those, and ran it into a hole I drilled into the glove box. I plug my USB memory stick into that.
Every month you download aero databases from the Dynon website. Put them on the stick, take it to the plane, plug it in, fire up the Skyview, go into the system menu and LOAD those. Takes about a minute.
Full Software Release updates take longer. Procedure:
Remove Fuel Pump fuse.
Master on. Skyview boots up.
AVIONICS MASTER AND AUTOPILOT SERVOS ON!
Go into system menu and LOAD the update.
Power down, Replace fuse.
Full software release updates also load software into the transponder and autopilot servos. That is why you have to have the Avionics and AP servos "on."
Read and follow the steps that Dynon gives you for release updates when they are issued. On this last one, there was an extra manual "transponder load" step, for example.
You will love the Skyview!
