backup camera options

[Lil CacAzn Nick]

so i just bought a factory nav for my car and will be buying an amp and having everything installed soon but I would really like to add a backup camera while I am doing all this. what are my options? do i have to use a factory camera? what do i need? is it possible to use an aftermarket camera? thanks.

Pretty sure you can use an aftermarket one, upload a pic of the back of the Navi. system so we can tell better.

Don't think there is an input for an aftermarket one on there.

you can probably use an aftermarket camera, you will just have to splice into the factory wiring harness for the video input.
