Hi All,
I have an 18 plate Karoq, I have tried several "Cheap" ie 50 to 80 ukp wired to wireless adaptors for android auto and found the following.
Wireless android auto needs android 11 or 12 to function correctly. There is no point sideloading a later version than the phone is designed for, its hardware is not up to the processing required.
It is doing a lot more than just sending google maps or waze data to the display.
The adaptors which work correctly use both 5ghz and 2.5ghz Wifi and bluetooth to connect to the phone, they need the bandwidth to move enough data fast enough.
The first one I used which worked acceptably was an Ottocast U2-X, this worked unreliably with my Samsung S9, frequent hangs and serious lag on map audio and controls.
I now have an Ottocast UX-X pro at about 150ukp with Samsung S20, this works with all functions, steering wheel buttons, voice control, waze or google maps, and utube music, with phone support simultaneously with very little or no lag.
Very occasionally it will freeze, usually in poor signal areas, needing the radio re booting, 10 second holding of the on off button until it restarts.
One point you wont find, listed or at least I didn't, the voice control operates as follows.
short press car functions, long press Ottocast functions.
