Sony picked Wednesday to revamp its in-car head units with a much heavier influence on digital sources in eight new devices. The CDX-GT565UP, DSX-S210X, and DSX-S310BTX all stream Pandora's Internet radio from a connected iPhone and go beyond just basic USB or Bluetooth audio. At least on the S210X and S310BTX, all the Pandora controls shift to the receiver, including the thumbs-up/thumbs-down to tune the recommendations.
