This is a feature in the TFT screen that can be switched on and off on all of the colour screens, XR with premium sound included. What you can do is have the screen on all the time or have it switching off after a few seconds like you have found. The way to change the mode it is in is by switching the ignition on to at least accessories and then with the radio switched on press and hold the volume control knob down until a beep is heard or the screen changes. Do this again and it will change back. I think its better to have it only on when you change a mode or volume especially at night. I wonder how many warranty claims might be made for a cutting out screen! hope this helps some. I wish you could do the same to the silver/green screens on the other models
