The best way to test it would be to remove the radio that is in there right now, and plug in the new one that you want to test. It won't be that hard to remove the current radio and plug the new one in quickly, it would be a lot easier than trying to test it otherwise.
You will not need any special cables or connectors. If you are going from one factory radio to another, it will be entirely plug and play.
You should not need any special tools either, other than maybe a socket set and a couple of screw drivers.
You shouldn't have too much trouble swapping out the radios, the hardest part will be figuring out how to take your car apart so you can get the current radio out, and I am sure you can find a guide online (P.S. here is the guide:
http://www.installdr.com/InstallDocs...PDF/466013.pdf). All you will need is the phillips screwdriver and 2 sockets, the other tools are only for an aftermarket radio installation. Just follow the instructions and you should be fine.
