Ideally all i'm after is the android auto side of things use waze as the app on cmdroid has decided to stop working. Lag and and the microphone I'm not to fussed about.Hi,
short anwser: I don't think it's ready to be released.
long answer: the app mostly works but there are some features that are still not available due to Honda Connect customization. For example, microphone (so google assistant), steering wheel buttons, phone call... these don't work. What works quite well is the android auto protocol, so you can use the apps that need only touch screen and audio (maps, youtube music, spotify...).
The experience overall on what work is good but it will never be like the offical app (or other porting) because of the Honda connect android version (4.0.4 is veeeeery old). There is some lag from the input and the response on screen. On top of this there are still many bugs to fix.
