I wish i could help you. Unfortunately there really isn’t a lot of info out there to go on. I can only seam to find general installation info. Not much for trouble shooting. when i installed mine everything worked perfectly but couldn’t keep the screen to stay on. it seamed to pop on...
I recently did this upgrade and having the same issues with the 8” apim. Has any resolved this issue somehow ? I’d much prefer to keep the factory apim if at all possible.
