BYD Prepares Next-Generation Wi-Fi 6 Infotainment System for Future Vehicles, FCC Filing Reveals

Electrical-Plum-751 | 2026-01-29 22:22 | 34 views

Hey everyone, was doing some digging through recent FCC filings and stumbled upon what looks to be the brains of a next-gen DiLink system from BYD. The filing is for a new central infotainment unit (model MTD421-A1) that's packing Wi-Fi 6, which is a massive upgrade. This should mean way faster and more reliable OTA updates, better in-car media streaming, and just a much snappier experience overall. https://preview.redd.it/m5wibwg06dgg1.png?width=1704&format=png&auto=webp&s=922d4e585ad96826e07c7056a2e0bc047856efb1 What's really interesting is that while the radio is tested for Wi-Fi 6, the specs hint at future-proofing for Wi-Fi 6E. Based on the confidentiality request, we might not see this in a production car until mid-2026, but it's clear BYD is getting serious about their in-car tech. Besides just raw speed, what's the one software feature or improvement you're hoping this new hardware enables for DiLink?

That will come with an annual subscription

I would just like for my car to just connect to my home wifi. It has no cell signal at home (parked in a basement) and so it doesn't get to do OTA updates while parked.

Yes, mine connects automatically.

Car only updates over SIM, not WiFi unless they are changing that in the future.

My OTA incremented v3.0.0 but none of the rest of the software updated. I'm still stuck on 2410 when I should be on 2507.

I've taken it into BYD and they did nothing.

r1chardj0n3s 2026-01-30 05:20

Yep. Gotta turn it on every time. And it doesn't appear to stay on when you turn the car off. So, what is it even for?

No shit. I did that. BYD told me to contact the service centre. Come on dude. Do you really think I haven't tried everything?

Mine turns off when I connect Android Auto, then turns back on automatically after I disconnect my phone.
