This is a Bluetooth Phone app launcher for Mekede 8227L based Android head units, may work on other models you can give it a try! You will get a toast notification if it does not work. I am publishing this so you can download from the store rather that search the net. This will enable you to add the radio shortcut to a custom launcher. If you get it working on another unit please send me an email so I can add to the list.
