Back on topic-
The lid is actually a bit of plastic, I cut the bottom off the original ashtray and glued the plastic inside then mounted the sockets, one is a normal cig socket the other a double USB, I didn't like cables flapping about as well and as the stereo is a fold out touchscreen every now and then the gps cable would get dragged into the stereo when it folded if i wasn't careful.
The discs are from Dick Smiths to enable a GPS (or anything else with a suction cup) to stick to the Dash, roundabout $10 for a 2 pack and hold things a lot better especially when the screen gets hot in the summer. These discs sometimes come with a new gps and use 3m adhesive pads to stick to the dash, also can be removed without any damage.
