This concept leads the wires from a your satellite navigation system to your 9 volt outlet using a smart adjustment of the dashboard panel. The wire can be easily stowed out of sight in a special gutter in the rear edge of the panel.
Picture of the problem situation: the wires of the satellite navigation system run across the dashboard. This looks messy and can hinder operating the car safely.
This picture indicates where the wires could be guided by a gutter in the back of the panel.
An alternative solution was to put a 9v outlet next to the centre speaker in the dashboard. The lid is used to wrap the excess wire around it.
