Try clearing cache of the Android Auto app. That should work 😀

I have issues with my S20. I get it to work once I've connected it via Bluetooth and then the cable by sending myself a text message from the phone. Sounds strange, but works for me. Can't find out why, but works 95% of the time

No funciona, ya lo intente.

Hola, tengo el mismo problema con mi S21 standar; mi carro es un T-Cross (volkswagen) del 2019. Con el S9 no tenía problemas, e incluso lo he vuelto a probar y no muestra problemas con este equipo, pero lamentablemente lo he regalado y ya no puedo usarlo. Con el S21 standar no puedo estar conectada más de 3 minutos seguidos. Probé 2 cables Samsung original (del S7 que conecta y desconecta el app, y del S9 que ni lo reconoce) y nada, además probé un cable T-Phox Flash serie 2 (USB 3.0) y ni lo reconoce,  pero con los 3 cables carga la bateria. Borre el cache del Android Auto y nada, también puse el celular  en modo programador y nada. Llevé el celular al servicio técnico, lo revisaron y dijeron que estaba todo ok. Por favor ayúdeme a solucionar este problema

I can't connect my swiss S21 Ultra 5 G to Android Auto using a SEAT Alhambra Bulit 2020. I've tried many cables, including all original Samsung USB cables from different Samsung phones. Then I have uninstalled all apps: Android Auto, Android Auto for Smartphones, Goolge Assistant, Google Maps. Then reinstalled all of them. Cache clearing didn't help either. Even a total factory reset of the phone didn't help any.  Also I got he latest Android Version plus I had my SEAT dealer to update the car radios software. Still no connection. The phone gets charged, but no Android Auto!  Really bad, Samsung!

So, did you get it working somehow? I've tried many things. Only thing is that I'm waiting for the September update from Samsung that might solve it.
