Why does my new stereo keep changing display?

I recently got a new stereo for my car. It is a JVC KD-X320BTS. When IIm driving around or just sitting listening to music it all works fine. But if I don't touch the buttons after a while the radio changes display and says random stuff like "usb for iPhone", and "voice recognition". It doesn't effect quality of sound or the performance. It's just kind of annoying. Is there anyway to fix it or make it stop and stay on the display I originally chose?

Here's a grand idea, READ THE F'N OWNER'S MANUAL!

My iphone is not jailbroken at all what could be the problem?
  • Why does my car stereo make a clicking sound when I charge my iPhone? I just bought a certified preowned 2009 Mazda Mazda3 hatchback.

The clicking gets faster and slightly higher in pitch as I push the accelerator. What's going on?
