The instrument panel for the RV-7A I'm building will have an Advanced Deck 4500s, a GNS430W, and a SL-30. It will use a Dynon D100/HS34 for backup. Both the 4500s and the D100/HS34 can be used for CDI (Course Deviation Indicator). I would like to have both the 4500s and the D100/HS34 RECEIVE information from the GNS430W and the SL-30 and I would like to be able to SELECT which CDI provides the OBS information to each NAV unit.

Is it possible to be able to select either the 4500s or the D100/HS34 to provide the OBS information to the 430W and/or the SL-30 while both the 4500s and the D100/HS34 display the CDI info? If so, how would this be connected?

Regards,

Roy
