When I installed from the market it put com.google.android.carhome-1.apk in the /data/app folder, is this the correct location?
When I go to the app from appbrain it shows it as installed but the open button is grayed out.
Reading the app comments it looks like you can't launch it independently anymore but will launch when placed in the dock, I have yet to verify this.
Works, but has to be in the dock.
