I'm a new hand in the car,and I just bought a Xtrons TD717G. But I am not familiar with the keyboard of it. I want to know what is PTY. Could you explain it in detail? Thanks.

 

PTY is just abbreviated from Program Type.The button can classified the types of radio programs automatically, and display the program type name(such as news,sports,etc), so that you can listen to your favorite program quickly.
