Today I drove to work listening to HD Radio (worth the price of upgrade from 5000>6100!), and got frustrated that holding down the L or R button on my steering wheel did not go to previous or next stations. I thought for sure something was broken.

Low and behold, yes, it worked!
No change was made to the PAD RP4-HD11. Nada. Zilch.
