Hello everyone, I am a noob so pls excuse my ignorance. I have recently bought the bigger oem 8” screen, the bigger nav box and the touch IDrive controller from someone for a good price. I thought it would be plug and play but the screen says No Signal and the “box” needs more connections. Can someone be kind enough to tell me if it is possible for me to install this and exactly what else I need to buy and how to do it. Thanks! I can Venmo you a bit of cash for taking up your time too!
