In the process of updating upper and lower screens to Android units. My particular unit also came with an upper glove box and new double button opening switch. I have the switch plugged in and the lower button work to release the lower glove box but not for the upper. There is an extra plug with the new upper glove box and I can't seem to figure out where it plugs in. Anybody upgraded and come across this? I also cannot seem to get my rear view camera image to show, All I get is a black screen when shifting into reverse.
