SendStation Systems has announced that its iPod Dock Extender is now shipping. The $29 accessory allows users to dock an iPod or attach dock-mounted accessories without removing the device from its case. SendStation has also relaunched its smartCharge iPod car charger with a lower price and new cable. The smartCharge, which now sells for $25, comes with a special audio-enabled USB-iPod Sync/Charge cable. “It provides superior quality sound through smartCharge’s built-in Line Out jack, for direct connections to the Aux In jack found on many car stereos,” according to the company.
