There are many problems with the px6 android 8.1 unit but the main problem is that it stuck at a blank 360 camera screen when starting the car if the car has not been started for more than 6 hours. Reset or restart did not help as it would just show a boot screen for a second and then jumped into the blank 360 screen again. Sometime the unit can reset by itself and got into the system after 5-15 minutes depending on how long the car has not been started. During this problem, I also lost the control of the page button on my steering wheel and the control did not come back even if the system finally booted up.
There is another infiniti user posted the same problem with this unit on his QX70 so I believe that it is a more general bug for the system to infiniti cars. I tried to contacted Phoenix radio but they never replied...... Can anyone who has the same unit share their intall setting?
Another problem is that in the door status when doors are opened, the door image does not align with the car image and the car image is like stretched....... This is a simple problem but they have never fix it even though it is reported to them several months ago..
Other problems are like When you use bluetooth music, you don't have any sounds from the system's sound output so you cannot have navigation sound and bluetooth sound at the same time, which was ok on the px3 but not the px6.
