You are lucky if they are really Android 11, not to mention Android 13.

The device info on all those HU are spoofed.

On my Android HU that was claimed to have Android 11 can't even install the Google Map that is Android 11 friendly version. Can only install previous version. Many features not available.

So take their claims with buckets of salt.

Look for TS10 processors.

Go read my review in the Car forum.

If you use Carplay / Android Auto, sound quality will be greatly affected 'cos it doesn't go through the DSP of the head unit. Sounds like crap.

Calls are not picked up through Carplay, but through HU's own bluetooth connection to the handset.

Crappy and confusing cos they are not implementing real carplay.

Suggest you go for proper product like Kenwood, might not have big 9" 10" screen but it's proper car play integration. Careful about one fake Kenwood android HU in shitpee / lapsapda going for 400 around there.
