Can't Remove factory radio
 

I have the keys required to remove the factory radio from mr 99 L but when I insert them in those holes on the sides of the radio and pull it just won't come out. what do I do?

You have to push out on the keys, that pushes the clips holding the radio in.

I posted this a couple days ago, here it is again. It explains how to pull the stock radio....

Make sure you hear a click. Then push out toward the doors on the keys and pull toward you. It should slide right out.:D

I had trouble the first time I tried it. I was pushing the keys in to far. Push them in just until you feel the click like Invalid_access said.

Thank you for your advice I will try it out and see if it works
