On to the Music App which I love! Its called TutuneMe from App Store!
The top playlist bar brings up this menu when you tap it, or you can swipe the top bar to go next/previous playlist.
Of course SIRI can play my playlists for me too, but sometimes you dont know what you want and this makes it quick and safe while driving! Tap on one of the large icons and the corresponding screen comes up. I should point out the colours and font sizes and album art size are all fully customisable. This is the standard Cherry setting with the fonts brightened up and made larger for good visibility in the car! Which happens to match the RNS 510 colours pretty closely out of the box! You can swipe in the centre over the album art/artists info, left or right to go next/previous track too!

Album view
Quick access to the audio routing from the bottom bar which also scrolls left/right to bring up different controls.
Thats all for now.. have some more pics I need to load up of the booster cradle, now the glue's dried. (pics at night!)
Will upload a video to youtube for tomorrow as well.
