New RDX, hooked up iPod Classic with USB connection provided. The on-screen (non-navigation/tech package) display shows a listing of "albums" which is numerical and not able to be searched; and the 'albums" include installed audiobooks. How do I control the selection of items to playback through the RDX controls? Or can I?

My wife's Subaru Forrester has a great display and allows scrolling as if I were thumbing through the iPod itself.

Thanks for any help you can provide.
