I tried that on mine before I swapped the head unit for an AVin unit. The viewing angle was wrong even though the seller said it was supposed to work on an e53. Based on the viewing angle the LCD was probably for a sedan where the screen is lower. On mine I had to lean forward to get a clear view of the screen. Sent it back said screw it and bought the Avin. Glad I did. Some of the best money I've spent on my truck.
