When Android 11 rolls out, the list of phones that can utilize cordless Android Auto will grow considerably. Google has actually upgraded Android Autos FAQ page (as spotted by 9to5Google) to add that almost all gadgets installed with the upcoming mobile OS will get the ability to connect to suitable in-car entertainment systems without a wire.
The upgraded page likewise keeps in mind that your phone should support 5GHz WiFi for wireless connection to work. Many modern mobile phones can currently do that, so you will not have a concern unless you have an older or a low-end to mid-range device, a few of which can only connect to 2.4 GHz WiFi. Take note, however, that the EU has additional regulatory requirements when it comes to using 5GHz WiFi in automobiles.
