EX5 EMI Split - REMOVE HELPER STARTUP
Usually unnecessary: update by installing the new APK over the old app.

Park in P at zero speed and exit Split to the home screen. Disable only the
EX5 EMI Split accessibility service, preserving all other services.
Removing the two system startup files requires ADB/root/remount via USB:
platform-tools\adb.exe root
platform-tools\adb.exe wait-for-device
platform-tools\adb.exe remount
Continue only if root and remount succeeded:
platform-tools\adb.exe shell setprop ctl.stop ex5split_helper
platform-tools\adb.exe shell rm -f /system/etc/init/99-ex5split.rc /system/etc/ex5split_helper.sh
platform-tools\adb.exe reboot
After boot, uninstall the APK using the head unit app list if desired.
Uninstalling the APK deletes saved profiles.
