How do yuo uninstall a cd reciever

I am trying to install my wiring kit in my car and to get to the RCA plugins pluged in to the back of my reciever.  I can get my Deck out because I need the special keys or tools that go on the sides of the reciever to take it out.  I have a JVC KD-GS720 deck i do you know where i could get the special tools that go on the sides to pull it out at?

Respond back soon thanx

JVC decks have side locks that need to be slid to each side by use of thin pieces of metal. If you have two thin butter knives or steak knives you can do it ( if you don't have the keys ). Take the face off the deck and also the trim piece. On the sides of the deck you will insert the " keys " ( make sure you are between the deck and the sleeve ) and take a small 90 degree pick  and pull the deck out by the front. Make sure that who ever installed the deck did not use metal strapping material in the back of the deck to secure the player, otherwise you will be pulling on the front of the deck for a long time.
