GNS 430 CDI does not change to VLOC while GNS 530 does

ISSUE DESCRIPTION

Description of the issue: The GNS430 always remains in GPS mode, impossible to change into VLOC mode. In aircraft with both the GNS 530 and GNS 430, the 530 is able to change between GPS and VLOC, while the 430 remains in GPS mode. Pressing CDI on the 430 will change the 530 between GPS and VLOC, but not the 430 itself. Screenshot from the default DHC6 but more default aircraft have the issue.
SU2 v1.4.20.0
