I’m using the 2d cockpit displays.  On the display it shows info for both VOR1 and VOR2 In the bottom corners.  How do you choose the currently selected VOR from the primary and secondary settings for the AP to follow?  If it was a Garmin g1000, there would be a CDI button.  I guess I’m looking for something like that on the 737 and 747.  Thanks!

Anybody know this?  I must be missing something simple.

If this is the stock 737 / 747 then no, there is no way to select AP nav source other than NAV1 & GPS. Only the most advanced payware aircraft have the ability to select NAV2 as the AP source. 

Thanks!  It makes sense since I couldn’t find a switch for it.
