Apple released this first version of the Universal Dock on October 12, 2005, along with the iPod Generation 5 that could display Photos and Video. In a press release, Apple described the Universal Dock as an “optional accessory” for the iPod:
“Optional accessories designed for the new iPod include: Universal Dock for $39 (US), giving users easy access to a USB port for syncing, IR support to work with the Apple Remote and a variable line out and S-video connections for integration within the living room.”
The 2005 iPod Universal Dock included the S-Video port and an infrared sensor for an Apple Remote (sold separately). Unlike earlier iPod Docks designed for specific models, the Universal Dock used Dock Adapters to support a wider range of iPod models with 30-pin dock connectors.
This iPod Universal Dock included adapters for 5 iPod designs sold at the time. Each adapter was numbered and matched to particular iPod devices:
- 3—iPod mini (4GB, 6GB)
- 4—iPod (20GB) and U2 Special Edition
- 5—iPod (40GB)
- 6—iPod with color display (20GB, 30GB) and U2 Special Edition
- 7—iPod with color display (40GB, 60GB)
This iPod Universal Dock could also accept other adapters listed on the packaging. Other supported iPod devices included:
- iPod (10GB, 15GB, 20GB)
- iPod (30GB, 40GB)
- iPod nano (2GB, 4GB)
- iPod with color display (30GB)
- iPod with color display (60GB)
An updated iPod Universal Dock was released in 2007 (it included a white Apple Remote, but omitted S-Video), and a 2010 version included new Dock adapters and the updated aluminum Apple Remote. This product line was eventually replaced by the iPhone Lightning Dock when Apple switched from the 30-pin connector to the Lightning port for charging and sound output.
