Sadly, I think the only format Dynon allows for traffic and weather is from the ADSB 472. When they were having problems coming out with the 472 as an upgrade to their single channel box they were considering allowing other formats but in the end did not. I certainly wish the industry standard GDL 90 format were allowed. Dynon has told me they could allow it but choose not to do so. I even told them I was willing to pay a license fee to offset their profit on the ADSB 472 so I could eliminate a box, antenna, weight and regain a port but they were not willing to do so. I continue to ask for this when I see them at Oshkosh but no luck yet.
