One of the most infuriating things about owning a classic car (other than jetting the carburetor) is getting lost in it. Satellite navigation is one of the best digital technologies in the modern suite of driving aids to come out of the past decade-and-a-half but unfortunately, integrated satellite navigation systems post-date most classic cars and those portable GPS units are far too unsightly to live on the fascia of 911 2.7 RS, for instance. Aftermarket integrated satnav is available but the units fall into a category of rather suspect design aesthetics.Neat fascia fit Porsche values the heritage of its cars and the committed customers who run classic Zuffenhausen products so to make life easier for air-cooled 911 owners Porsche now offers a satnav unit that masquerades as a retro-styled radio.The unit, rather unoriginally called the Porsche Classic Radio Navigation System, has been packaged to ensure a neat fit in the classic 911 fascia. The display screen is mounted in the middle, flanked by two round control knobs.Boasting the appearance of an analogue radio receiver, this latest Porsche option is retro done right. It will be available from October and retail for about R6000. Never again will you find yourself on a boring freeway instead of a challenging mountain pass in your 911 2.7 RS while trying to piece together that perfect drive in a foreign country.
