Compatibility, latency, data usage and privacy questions answered.

FAQ Updated August 28, 2026

Do I need to modify my car?

No. CarCast is pure software — no hardware or system changes required.

Which cars are supported?

Any head unit that supports CarPlay, HiCar, ICCOA CarLink or EasyConn. 200+ models are confirmed working. Check your head unit manual or simply try connecting.

How bad is the latency?

  • Wireless: under 100ms
  • USB: around 50ms

Comfortable for navigation, music and video playback.

Does it use mobile data?

No. Frames travel over your local network or USB. Nothing touches the cloud and no mobile data is consumed.

Can I watch video while driving?

Video is hidden while the car is moving and restored once parked, per traffic laws. Navigation stays visible at all times.

Can I use other apps while mirroring?

Yes. Mirroring runs on its own channel — WeChat and calls are unaffected. Incoming calls lower the stream priority and it recovers automatically.

Is my data safe?

Everything stays between your phone and the head unit. No cloud, no tracking, no personal data collected.
