Review on Enhanced Performance Android Car Stereo for BMW 3 Series - 2021 Newest Android 10 Head Unit with Carplay, Android Auto, WiFi, Backup Camera Support - 9 Inch-GA9450B by Kevin Parker

My head unit doesn't work properly, it worked fine for about a week but suddenly the Apple Car Play function stopped working, along with the Bluetooth and radio everything is set up , as it should be and nothing has been tampered with, cut or altered in any way so my only cause of the problem is a defective product, also straight out of the box there were discolored pixels on the top right side of the screen like it was a trash can fell out or got wet please get back to me, product worked great for the most part, if there is a way to replace the main unit that would be great. I hate wanting to give a bad review what I paid for last thanks
