Hi there,
Im sharing my experience trying to install a new dudu7 on my Mazda cx3 2019 so far:
It was very hard for me to connect all the wires because there is not space enough between wires, the case frame, and the head unit. Eventuallly I did it.
The first time I could turn on the machine the sound volume was very very high. "Wellcome administrador" I think it said.
I tried to low the volumen with Mazda oem controls but they dont seem to work. So Canbus wasnt ok. I tried to search in settings but I couldnt see my Mazda model and I dediced to try next morning because it was late night...
Next morning my car didnt start... I unplugged everything and install again my old oem radio and the car didnt start either. Dead battery. I could recover it with a powerstarter but there is a battery warning menssage and istop doesnt work.
So I dont know what to do next. I dont want to install it again before I know what could happened.
If someone could help I will thank you a lot.
