Google Car Home for rooted Android devices
Comments (2) 
For some reason, Android versions greater than 2.3 no longer come with the Google CarHome app. This is an app that gives your phone a simplified interface for easier use in-car.
To install on a rooted device, download CarHomeGoogle.apk
Copy it to /system/app, set permissions to -rw-r–r– (644) and user/group owner to root.
