Here’s how I mounted my GPS in my C5. It happens to be a Garmin nüvi 855, but I imagine the procedure would work with other GPS units as well.
Instead of mounting the GPS in the center of the windshield or elsewhere in the central area of the console, I chose to locate the GPS to the left of the dash cluster next to the “A” pillar with the unit’s supplied suction cup mounting system.
The wiring configuration provides very little “cable clutter” and there’s no need for drilling holes, as the setup uses existing dashboard attachment screws. The cable can be removed in about ten seconds leaving no traces of having been mounted.
In practice, I found the GPS is just as user-friendly and less distracting than a centrally mounted unit, and provides better central forward visibility.
Photos 1, 2 and 3 show the placement of the device and photos 4 through 8 show the wiring layout. Photos 3 and 4 show all the visible cable when in use.

The wiring starts at the 12v DC plug and drops underneath the dash area. (For those with “speech recognition” GPSs, note the mounting of the remote control unit on the steering wheel.)
pic5
The first mounting point is an existing screw underneath the dash. I used a plastic wiring clamp and modified it, (clipped it with a wire cutter,) to allow the wire to be held in position, but to be easily removable.

The wire continues to a clamp mounted to the other existing screw to the left. I imagine any cable slack could be looped around here.

Then the wire works its way up towards the dashboard.

This photo shows how the wire wends its way through the gap between the door and the dash cluster. The wiring is not affected by closing the door, and terminates at the GPS unit.
