What does RPT mean in a car?

[RonanMarie]

RPT in a car stands for repeat or loop playback, which is a button indicator on the car audio system. RPT is typically found on multi-disc CD players, and it usually requires holding the button down to activate the function. If you have a single-disc CD player installed later, this button will be non-functional. There are many buttons on the player, each with different functions, including: 1. SEL, the menu selection confirmation button, often found on the multifunction steering wheel; 2. AC, the air conditioning cooling switch; 3. VOL, for adjusting the volume; 4. MUTE, for muting the sound; 5. MODE, for switching modes; 5. SE, for the cruise control function.
