SendStation Systems today announced that its Dock Extender for iPod has begun shipping. The Dock Extender allows users to dock the iPod or attach dock-mounted accessories without constantly peeling the iPod from its case. Dock Extender for iPod is priced at US$28.95. The company has also relaunched smartCharge, its popular iPod car charger, and cut its price — it now comes bundled 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. The new smartCharge works with all iPods with 30-pin dock connector and the 1st generation iPod shuffle. It’s available now for $24.95.
