Waze no longer supports SDL (Simple DirectMedia Layer) which is what Ford's SYNC 3 uses so no more integrated Waze via Android Auto in the wife's Mustang.
It hasnt been working for a while. I believe there was a workaround on getting to force use the older software but was not perfect either.
Waze itself is actually being integrated with Google Maps. I have gotten the police radar notifications when using Google Navigation as well as other stuff like the re-routing in heavy traffic areas.
