Everything DashArc does
on your BYD.

DashArc is the most complete app for the DiLink head unit in BYD cars. It unlocks the head unit for free, adds an app store with YouTube, Netflix, Prime Video, WhatsApp and Instagram, brings Waze navigation to the instrument cluster, records all four cameras as a dashcam and sentry mode, and lets you see, hear and control the car from your phone, wherever you are.

On your phone, DashArc installs straight from the portal to your iPhone or Android home screen; on a computer, it opens in the browser.
