Installing a navigation system is a tad more difficult than installing a
basic radio. The difference arises if the system requires a speed signal.
The GPS may use this signal to estimate the car's position when the signal
to the antenna is not available (i.e. in a tunnel, in a city with high
buildings, etc.). To gain access to the Cappuccino's speed signal some
medium level installation work is required.
