I have been reading your messages and contributions in this post and in your web page so thank you, it helped me a lot!
I would be interested on installing this launcher in my HU, I have downloaded ("gongban_YT57xx_SplitScreen-ui17-v1.73_42e18e94_ota.tar.gz") but i dont know how has to be installed because is not a "normal" apk, needs to be installed as an update or something like that?.
If I want to get back how can be uninstalled or changed?
I recall just put the tar.gz on USB stick and use same firmware upgrade menu. "Android Upgrade" button will be available. Make sure USB stick does not contain any firmwares or other update tar.gz files or it will install those too. This launcher install is much quicker than firmware updates. I think shows an android robot update animation, reboot and done.
I recall this launcher just overrides the default. xyauto has a lot of launchers with naming overlap (usually called "launcher1") Android's default app settings show how many launchers to choose from and which is default.
There is a "Other Settings" tab on the latest firmware's Car Settings app (don't know when introduced). This is where you set the nav app for this 3 split window UI. See attached pic
For Nav choice, I've settled on Sygic for free nav without cellular data connection on my HU. It does 2 things correctly which the other 2 free options (google maps, here we go) don't do.
- Will switch to night theme automatically. Latest google maps + HU's android version don't do this unless you are navigating a route. White background google maps is very bright for dark night use in my car.
- Sygic will automatically put map in 3D driving mode when driving. Google maps and here we go stays in 2D north up mode if not navigating a route.
But free sygic missing turn by turn and don't have google's nice search capability (require network so basically need a cell plan)
