GI 275 conflict with PN101

[turbosuper]

I am getting a conflict between a Garmin GI 275 and a Collins PN101, which
is causing the OBS resolver to not function between a GTN 750Xi and the
PN101 HSI. With the GI 275 powered off, the OBS resolver from the PN101
displays correctly on the GTN. Currently it is setup as follows:

GTN 750Xi: GTN 1, GI 275 present
GPS 175: GPS 2, GI 275 present

GI 275: GI 1
NAV 1: GTN 750
GPS 1: GTN 7xx
NAV 2: Composite(KX165A)
GPS 2: GPS 175

With this configuration the PN101 OBS resolver does not work. I tried
removing the GTN from the GI interfaces and just setting the GPS 175 and
Composite for the KX165A, but the OBS resolver from the GI 275 does not work
on the GPS 175. I also tried disabling "Course Selection" to the GTN on the
GI. The GPS 175 is hooked up via Ethernet to the GI 275 as is the GTN.

The solution is to disable "Transmit Selected Course to the GTN" in the GI 275 CDI/MFD interfaces config for GPS1: GTN 7xx
