* Now connect your slave phone to the car's USB Media slot via cable. This acts as a Wifi receiver for your car's head unit. * Switch on mobile hotspot in your master phone and make the slave phone connect to it.This is how your slave phone would receive commands from master phone and slave phones apparently becomes a forwarder of command. From the drop down list, enable ' Start head unit server' and then exit from the app.įor some android versions, you need to click on 'About' in AA and click on the 'about android auto' option ten times for the developer option to open. You'll see a menu list appear on top right corner of the page. Keep tapping on the text 'version' under the ' About ' tab till the developer options open. Here you need to enable Developer options. * Now go to android auto (master phone) settings in your android auto. In case it doesn't work for you, you can drop a mail to for refund. I presume it's a negligible amount and one can go ahead keeping that in mind. Please note this is a risk(spending 70 odd Rs.) you're taking as there could be many things that could go wrong. Buy the app and install it in slave phone. *You'll find an app by the name AA Gateway in xda labs. You can login into xda app with Google account or create a new account. * Install XDA labs app and AA Gateway app in your slave phone. * Install Android Auto in your master phone. Here's a step by step procedure which seems to be easy. With my car having wireless phone charger, I feel it's still worth the effort and investment as your master phone is free to be moved around with no cables attached. For me with bit of trial and error, it finally worked.

Let me warn you it's either a hit or miss. * USB cable to connect your slave phone to car's USB media slot. * Car's head unit that supports Android Auto (via cable) In that context, one can say it's not a totally wireless solution but your master phone is freed totally. It still needs a slave phone to be connected via USB cable. This is what I learned and figured out after combing through the internet - xda forums and android community. I don't have the technical know-how to explain it in depth. (: Convert wired Apple CarPlay to wireless. Since the time I learned about an adapter that makes apple car play go wireless, i've been on the look out for a work around that makes AA work wirelessly too. For that, the car should have an inbuilt wifi. Off late there are many head units like Kenwood etc that supports AA wirelessly. And most of us always wished if it could function wireless. But the need to connect it via cable is a pain point. Android Auto has been a big boon since it's advent.
