Just two short years after announcing its plans for in-car music streaming, Pandora has finally begun to trickle its way into in-dash receivers. The digital music service can now be accessed through four of Sony's latest connected car stereos -- the DSX-S210X, DSX-S310BTX, and the SiriusXM-compatible CDX-GT660UP and CDX-GT565UP. The DSX units connect to Pandora's smartphone app via "an integrated Tune Tray," while the CDX models employ a no-frills USB solution, making your suite of personalized music stations an on-road reality. Although all of the receivers offer integration with the iPhone, only the Bluetooth-enabled DSX-S310BTX links Android and BlackBerry users to Pandora's streaming cloud. Of course, if you're looking for an additional means of accessing music on-the-go, you can always opt for FM radio. Full PR after the break.
