Ok so here is what you need for this to work: A rooted phone between android 6 and android 8.9. There is many ways to root, plenty of youtube videos. Try these. Once rooted, in your phone settings go to about phone and tap on build number 7 or 8 times until it says you've unlocked developer options. Go back and into developer options and make sure usb debugging is on. Now back out and go into security, make sure unknown sources is checked. Download the phenotype patcher (AA_Phenotype_Patcher_0.4.apk) from your phone's browser. It IS an apk so it will be able to install. Download AA mirror plus (https://drive.google.com/uc?authuser...xport=download) and your JB4 app. Install both apps then run the phenotype patcher. Click the top right corner and click apps list. Now click AA mirror, AA mirror plus, phenotype patcher and android auto. Open the AA mirror app, click screen settings and change rotation to FORCE and 90 degrees. Plug into your car, tap android auto, tap the little app switcher gauge icon, and select AA mirror plus. There you go! Proof it's working.
