My car has the Phoenix 12.1 Android PX3 radio in it. It was working fine up until a couple days ago. So originally all the AC controls worked fine. Then I shut the car off and turned in for the night. Come out the next morning and the fan is still blowing on low and the AC is on, not now there is no indication of fan speed or temperature on the screen and pressing the buttons changes nothing. I can still turn the AC on and off and control the defrost vents, but no fan speed or temp. Any ideas? I believe this problem to be software related since all the other Canbus features appear to be working fine. Is there a firmware/MCU/app update I can do to try and reinstall the AC controls portion of the radio? Or does anyone have any other ideas? Before anyone asks, yes I've tried changing the settings as suggested on Phoenix's website. No change. I can post pictures of my System info screen and what my AC controls look like.

You said to disconnect the battery then install the apk. What is apk? I bought this unit used and everything works fine but it will not go from hot to cold. It will work on the cold side with A/C just fine but will never get hot
