I did this on my g35, I'm doing it on my turbo EK. Got a FLIR thermal imaging night vision camera for a 99-03 Cadillac Deville, install a 5" monitor above my CD player and install the camera behind the grill.

Cadillac camera is pretty expensive, usually sells for $800-1200 on ebay but I found one locally for $300. Be careful when buying the camera, there are 2 versions. 2nd gen version is smaller and better. 1st gen version had a bad seal and water would get in it and it would rust out all the electronics inside (don't buy). I've had four 2nd gen version cameras and they all worked fine.

Here is a video of the camera working @: www.007licenseplate.com/nightvision/
