Sony has been big on smartphone integration for car audio lately, having already launched its MirrorLink receivers earlier in the year for the more well-heeled drivers among us. The company is bringing that mobile tie-in down to Earth through a new quartet of in-car CD receivers. The MEX-GS600BT, MEX-BT4100P, MEX-BT3100P and CDX-GS500R all bring in App Remote, which lets the faceplate buttons steer local music or Pandora streaming radio coming from Android, BlackBerry, iOS and Walkman devices paired through a Bluetooth wireless link. The old-fashioned USB connection is still on offer for these and the HD Radio-toting CDX-GT710HD, while the whole collection can graft on the optional SXV200V1 tuner to carry the full Sirius XM satellite radio lineup. Differences across the line aren't completely clear from Sony's wording, although both the MEX-GS600BT and CDX-GS500R carry two USB ports as well as 5-volt RCA preamp outputs. You'll be waiting awhile to slip any of these receivers into a DIN slot, regardless of which one you pick: the GS500R ships in October for $199, and the rest hit the shops in November for between $149 to $249.
