Porsche executives must surely know that older 911 owners are averse to upgrading their sleek machines, which is why engineers at the automobile firm decided to roll out the Classic Radio Navigation System that can be retroactively fitted into the dashboards of 911 models that were built between 1963 and 1977. In other words, if you happen to own a 1963-1977 911 model, then you are able to experience modern-day navigation within a radio that will slot in nicely without the need for boring new holes or other additional touch ups. €595 is the asking price for the Classic Radio Navigation System, and we suspect it shouldn’t be too much of a problem to cough up that amount for a true collector. Hopefully the mapping software that ships with it (if any) will have large fonts and clear readouts to cater for the expected age group of its owners.
