OPEL-BLP is a proprietary automotive digital radio and audio system developed by GM for Opel vehicles. This system is based on Blaupunkt’s radio architecture, which is integrated into the car’s computer systems. This enables audio and radio controls to be accessed via the car’s main computer, allowing for greater levels of entertainment. The system includes digital tuning, a six-disc changer, fully integrated iPod audio integration, MP3 and WMA file playback, and hands-free mobile phone capability. Other features include customization using a color LCD screen and buttons, internet access through a Wi-fi hotspot and compatibility with mobile phones. The most recent version, the OPEL-BLP3, features an all-in-one navigation and multimedia controller.
