Everyone can try my VIM3 ROM for car usage.
I activated UART GPS support.
ROM supports all USB and UART receivers, just need to add speed and port in /vendor/build.prop file, for example:
ro.kernel.android.gps=ttyS3
ro.kernel.android.gps.speed=9600
U-blox receivers are defined as ttyGPS. Also added all USB serial drivers in kernel (PL2303, CH341, CP210X, FTDI_SIO).
The maximum number of steps to adjust the volume, everyone can set the desired volume value, need to adjust the lines “ro.dmf.media.levels=30” - multimedia channel, “ro.dmf.notification.levels=15” - notification channel, “ro.dmf.alarm.levels=15” - alarm channel in the file /vendor/build.prop.
Shutdown by holding the POWER button for a long time without the confirmation menu.
My next steps:
Need to add VESA resolutions and ignoring an active Bluetooth connection, playing music, and a network connection for fast enter to deepsleep mode.
