Independent app for the BYD Seal U
The Seal U is the BYD Song Plus as it is sold in Europe, the UK and other markets: the same family as the car DashArc is developed and tested on every day. Waze on the cluster, live cameras on your phone, dashcam and sentry mode, remote control and YouTube, Netflix and WhatsApp on the head unit.
WHY DASHARC
Runs right on the Seal U DiLink head unit: no mirroring, no dongle, no WebView.
The DashArc Unlocker enables app installs and installs DashArc. No laptop in the car.
Live cameras and sentry mode stay available in stay-awake mode, with an eye on the 12 V battery.
New versions arrive on the head unit itself, with automatic installs if you want.
Try everything on your car before paying. Then a one-time lifetime license.
FEATURES
Everything below is already in the app. Tap a title to see the feature in detail.
The Waze route shows on the instrument cluster, in front of the wheel, with the next turn always in sight. The head unit stays free for music or your passenger.
The Seal U shares the 12.3″ instrument cluster layout of the Song Plus, DashArc’s reference display: the Waze map, lane guidance, alerts and maneuvering cameras show at full size next to the driving information. See the cluster map guide.
Watch the 360° view from anywhere, in your phone or computer browser.
All four Seal U cameras recorded into a single 2×2 video, while driving and while parked.

Yes. BYD sells the Song Plus as the Seal U DM-i (plug-in hybrid) and Seal U (electric) in Europe, the UK and other markets; in Australia and parts of Asia the same family is called Sealion 6. DashArc treats them as one car. The Portuguese page for Brazil is the BYD Song Plus page.
DashArc supports BYD plug-in hybrids and EVs with a DiLink head unit. On the EV, fuel information simply does not show.
The DashArc Unlocker has been tested on DiLink 3 head units from Brazil (system 13.1.33). European head units can use a different route to enable app installs: see the regional unlock guide. After that, DashArc and its app store work the same way.
Yes. DashArc draws the Waze route and turns (via Android Auto or CarPlay) on the Seal U instrument cluster, with no phone mirroring.
