Satellite navigation is now standard in the Vauxhall Signum.

The system features a four-disc CD auto changer with nine speakers, CD-Rom based satellite navigation with GPS positioning, voice direction, auto re-routing, a mono-chromatic display and a choice of route types.

Previously available as a £1,400 option, the same NCDC 2013 system will feature in the three trim levels, Elegance, Design and Elite.
