need advice stock stereo

At auto parts stores here in the states, they sell the removal tools to remove the radio.  They cost less then 5 USD.  I really suggest purchasing them.  If you try the wire and mess up the pieces on the side of the radio, you will have lots of trouble getting it out.  When you get the keys, simply insert into the holes and push in untill you hear a click.  Duplicate for the other side.  Once both keys are inserted, gently pull the left key left about an inch or 2 and the right key to the right about the same.  Then pull the radio out of the dash.

ok fair enough, thanks for the info
