I currently have the 2005 Roadster with the Bose system and w/Nav. I just bought the z last January and the lid for the NAV has never worked, the dealer said there was a connector behind the cluster gauges that was disconnected. When it is reconnected the NAV / Radio will not work. I have removed the Cluster C trim and found out the ribbon connector to the Lid motor is missing. I have no idea, where to look, it is not visible in with the other 2 connectors. Anyone know where it comes from. Like I said it connects to the Lid motor circuit board. Also the Radio now does not work, I only get the one station and the radio will play whatever I insert in it. The volume works, but none of the buttons on the front of the radio work at all? I am thinking the radio is toast, but thought I would ask.
