Scott Millhouse,
Was there continuity between SkyView display pins 16/17/18/19 and the USB socket? The USB socket numbers 1,2,3,4 on Van's schematic do not match up with standard USB pinouts. That makes me wonder if the schematic is labeled wrong or if the USB socket is actually wired wrong.
Standard USB pinout:
1 RED +5 Volts 16
2 WHITE Data -18
3 GREEN Data +19

Bill ... I too was worried about breaking the typical USB flash drive plugged into the USB port under the instrument panel (at this point mine is working flawlessly so continue to use it) and was lucky to locate some tiny PNY 32G flash drives. Picked up two of the ones shown in the photo below and rotate them every month as map updates come along. I placed a rivet next to the flash drive for a visual size comparison.

Are you sure it goes directly to the Skyview
Pretty sure. I suspect that the USB wires from the SkyView go into the backshell of the EFIS D-Sub on the AV-50000A. But the USB wires do not actually connect to the AV-50000A. Instead, they make a U turn, come back out of the backshell and connect to the USB receptacle. That is my unverified theory. You can check it out yourself by taking the backshell apart.

I see what you are looking at. It is a visual anomaly. Reference the Vans Skyview schematic and you will see a direct termination to 16,17,18,19 of the 37 pin Dsub at Skyview. I had to run wires from my co pilot Skyview for USB to update new versions to second screen.

I drilled a hole large enough in the map box and installed a rubber snap bushing for the usb cable. Simple.
Me too. Works great.
