How to Change Time on Alpine Radio

The built-in clock is one of the most underrated of a car stereo.

While driving, it’s better to check time on your car stereo’s clock rather than on your wristwatch or smartphone.


It’s because it allows you to see the current time without diverting your focus.

In most vehicles, the clock is powered by the car battery. That’s the reason it remains accurate even when the vehicle is off.

But what if your battery is fully-drained and you need to jump-start the vehicle?

Well, in that case, the clock will stop working. And you’ll have to set the time once your vehicle is working again.
