VOR problem with GTN-650 and Skyview

[sstearns2]

I have a GTN-650 running through the ARINC-429 box. The VOR will work via the bearing pointers, but the "HSI SRC" will not toggle to the VOR.

The ARINC-429 VOR signal is clearly getting to the Skyview since the bearing pointers work, but why will the "HSI SRC" not toggle to the VOR? The "HSI SRC" will only toggle between the GTN-650 GPS and the Skyview GPS.

Any ideas?

Thanks!

This is as designed. From page 12-8 of the install guide:

Setting ALLOW AUTO SWITCH: to YES (LABEL 100P) (which is the default, including after
upgrading Software to v10.0 or later) allows the 430/530 to tell SkyView to switch from GPS to
ILS or back when on an ILS overlay approach - SkyView will display whatever mode the 430/530
tells SkyView to be in. When in this mode and not on an approach, switching between the NAV
function and GPS function must be performed from the 430/530.
If you want to manually select GPS and NAV from the 430/530, as you have done prior to v10.0,
SETUP MENU > SYSTEM SETUP > ARINC-429 > ALLOW AUTO SWITCH: NO

So, if you have AUTO SWITCH on YES, SkyView obeys the CDI button on the GTN. The advantage to this is that if you load an ILS approach in the GTN, the GPS will give you guidance to the FAF, and then will auto switch the HSI to the VLOC for you. In this mode, you have only a single selection on the HSI for the GTN, and then it will show the GPS or VLOC based on what the GTN is configured for.

If you set this to NO, then you need to switch manually via HSI SRC even when on an approach.

That's it! Thank you.
