Verdict: Android Auto is unverified for Maextro in the official S800 sources checked. The HIMA S800 pages show China-market cockpit and Huawei/HarmonyOS phone features, but we did not find an official Android Auto claim for Maextro S800.
Does Maextro S800 support Android Auto?
Do not assume it does. HIMA's S800 configuration highlights phone charging, Bluetooth phone key, Huawei UWB phone key, StarFlash phone/watch key features and HarmonyOS 5.0 requirements for selected functions. Android Auto was not found in that official configuration pass.
Does HarmonyOS replace Android Auto?
It can provide native cockpit and phone features, but it is not the same as Android Auto. Google says Android Auto needs a compatible car or stereo, a compatible phone and supported country availability.
Will Android Auto work on a China-market Maextro in Europe?
Only if the specific S800 software exposes Android Auto and the phone/country conditions are met. Google's country list includes Poland, Germany and Spain, but not mainland China. A China-market S800 therefore needs proof from the actual vehicle.
How do I check Android Auto before importing a Maextro?
Ask for a video of settings, projection menus, USB data ports, Bluetooth/Wi-Fi pairing, Google app behavior and software version. The seller should connect an Android phone and show the Android Auto icon or launch flow. For Apple users, read /en/blog/maextro-apple-carplay.
What can I do if Android Auto is missing?
Use native HIMA/Huawei features where practical, ask the importer for an official region/software route, or choose a specialist-confirmed aftermarket solution only after privacy, warranty and safety checks. Avoid relying on unsupported firmware changes.
