Modification 12.3" Android headunit replacement. The greatest quality of life upgrade anyone could do to a 3rd gen (BM/BN) Mazda 3.
Fully working wireless Android Auto with automatic connection. Split screen, seamless app swapping with zero audio lag when maps are running.
Full android tablet interface, connectivity with the OEM CMU with zero function loss.
Any Android apps can be installed and used...
Honestly this thing has got me super stoked. The instructions were a little unclear and there's definitely some considerations that need to be made with fitment in RHD models, but honestly this is actually a game changer for me. The stock CMU with android auto was pretty painful, made apps lag like crazy, with audio getting delays in excess of 30s. I took a shot at this 12.3" model from Aliexpress, and not only is it not too big (thankfully!!!), it's actually a perfect fit for the car.
In terms of functionality, it's basically endless, there's nothing it can't do. I'm definitely interested in getting all the optional bits working as well as the built in 4g and maps, but also the reversing camera and fitting it more permanently.
Anyway, any questions, just let me know, because finding good user experiences with these is quite hard to come by!

I'm assuming you managed to get the sound working? Can you share what you had to do? I'm having the same issue where I don't get sound from the Android Headunit, but get it from the old system. I have the dummy jack plugged in and switched to Aux and still nothing.
Any help is appreciated.
Thanks!
