If you’re looking to set the clock on your Pioneer car radio, there are a few different ways to go about it. The first option is to use the main menu on the car radio. This will allow you to access all of the different functions and settings on the radio. If you don’t have access to the main menu, you can also use the clock button on the face of the radio. This will take you directly to the clock setting screen. Once you’ve located the clock setting screen, you’ll need to select “Clock” from the list of options. From here, you’ll be able to set your time zone, date and time. ..
