Got mine today, works great with my Sony alarm clock radio, looking forward to music instead of DJ talk greeting me in the morning. Haven't tried it in a car yet, because my wife's Outback and my Wrangler have USB jacks, so I'm justing using the standard cable in those. For $20 cheaper I'll just pickup an extra cable to keep in her car, and thrown one of the gazillion 30 pin cables I own in mine for compatibility.
