Hello,
I just found this forum and thread. I bought a Android 9, px6 unit from Aliexpress. AOTSR was the reseller. I'm working through the install, with no instructions, and came across some questions and issues. My CTS-V is a 2009 and it came with the Pop Up Nav/ Bose.
1) I switched over the climate control board. It is mostly working but the back light on the passenger LCD does not come on. The buttons on it work, and you can even read the LCD faintly. Driver side works fine. I switched the Driver side lcd along with the cable to the passenger side electronics board plug and the problem followed, which led me to believe either the board is bad or there is some setting I am missing. Anyone else come across this?
2) My temp control units also display in Celsius. I see this is common. Any fixes for this yet?
3) The unit said it came with built in apple carplay. I can't get it to work for the life of me, wired or wireless. They included a unmarked dongle which may or may not be for carplay. It is rectangle and shiny black. One end has a male usb cable. The rectangle has a female usb cable along with a 3.5mm jack. I tried every combination of usb connections possible, both with and without the usb dongle in line. I don't even know what app to open. The menu has one icon called "Car Auto" that doesn't do anything. It's almost like the app behind that icon isn't installed. There is another icon called "Phone Link". This opens up an app called easy connection. I got this to work for screed mirroring, both wired and wireless but you can't use the touch screen.
Any help would be greatly appreciated!! Thanks!
