If you experience this please contact Avidyne Tech Support for guidance on this issue.
Functionality of the Radio is not affected but will display Non-Conforming Software in the Info-Software Page.
The Part Number and Revision Values for the VHF DSP must be visually verified to confirm conformity with the software update.
For IFD5XX/4XX S/W versions 10.2.3.1 & 10.2.4.1 the values are:
P/N: 510-00316-000 | REV: 05
This can only be remedied by sending the IFD into Avidyne for Repair.
This will cause all subsequent software updates to flag the VHF DSP App as non-conforming.
