Blaupunkt also used the brand "Velocity" to sell products aimed at the top, audiophile end of the market. Audi, Volkswagen, Porsche, Mercedes, Proton, Vauxhall, Pontiac, Holden and BMW all fit Blaupunkt (now simply Bosch) products into their cars, often branded with the car manufacturer's own mark (e.g. The VW Gamma, Audi Symphony or BMW Business CD lines), with Fiat using them, occasionally unbranded but generally unmodified. Some later Holden Astra models are fitted with Blaupunkt systems (with others being produced by Delphi Automotive). Blaupunkt also specialised in coach installations, selling TVs, multiple-speaker setups and PA equipment to that industry. That part of the business has remained with Robert Bosch Car Multimedia GmbH, a 100% subsidiary of Robert Bosch GmbH, and the Blaupunkt branding is no longer used, even on 'hidden' stickers.
