Well, speaking for myself, I'm using NavRadio for nearly five years now with several headunits, and with Dudu 7 it would be around 10 months. So I've tested it well enough, I guess. And as I said, NavRadio simply cannot handle RDS functions any better, because it doesn't have access to all the necessary data (ideally full RDS stream, or at least full RDS AF table, RDS error rate, radio signal etc.) and it depends on the RDS and radio functions available from firmware. So it shares the same radio base functions like stock radio app, therefore it will work the same way. With the only slight exception of FYT 7862 units, where Kotix managed to somewhat reimplement the AF function with RadioProxy companion app...
That said, AF and other RDS functions (namely TP/TA which on Dudu7 doesn't work at all) depends on firmware and needs to be addressed by Dudu developers.
