Скачать или смотреть JOYING HDIM In & Out EXPLAINED: How to Connect Your Car Stereo？

Did you know your JOYING head unit can do more than just radio and GPS? Let’s look at the HDMI In and Out functions.

In this quick guide, I show you exactly how to use these ports. Learn how to use the HDMI IN to watch videos from external devices or use the HDMI OUT to extend your display to rear-seat monitors.

HDMI IN (Connect External Devices)
The HDMI Input port allows you to connect external devices directly to your head unit. This means you can:

Screen Mirror: Connect your smartphone, tablet, or laptop to display apps, videos, or presentations on the large screen.
Gaming: Plug in a gaming console (like a Nintendo Switch or PlayStation) to play games on the go.

HDMI OUT (Expand to Rear Displays)
The HDMI Output function allows the JOYING 6490 to send audio and video to external monitors.

Passenger Entertainment: Broadcast movies or shows to rear-seat headrest monitors to keep passengers entertained on long trips.
Dual-Zone Viewing: Play different content on the main screen and the rear screens simultaneously (depending on app support).
