I had this when I first retro-fitted my Navi950, it was the aerial connection by the pedals, behind the kick panel. The cable was not 100% pushed in.
There might also be an aerial splitter fitted to your car, mine has this for the Intellilink, just above the kick panel behind the dash
Could also be any aerial connection or the roof aerial itself
