If you’re looking to set your car stereo’s clock, there are a few different ways to go about it. One way is to use the car’s built-in clock. To access it, press and hold the “info” button on your stereo until the clock display pops up. Another way is to use a portable digital clock. You can find these at most convenience stores or online. Plug the clock into your car’s USB port and wait a few minutes for it to sync up with your stereo. If neither of those options work for you, there are also manual methods you can try. The first step is to locate your car’s time zone setting. This can be found on the driver’s side door jamb or in the glove box. Once you have that information, subtract 12 hours from it (for example, if your time zone is Eastern Standard Time, subtract 6 hours from that number). That number will be your car stereo’s hour setting (for example, 12-6 would be 6). Next, find your car stereo’s minute setting (for example, 60 would be its number). Finally, set that number as your timer’s start time by turning it all the way up or down until the timer icon appears next to it. ..
