I just got a new 2005 4runner and got the 6 speaker standard CD/Tape player radio. I want to replace it with the JBL radio that has the 6 disc changer in the unit. How do I take this first radio out of the truck without ripping up the dash? I am also assuming that this other 2005 4runner JBL radio will fit right in where the other one was with no problems and no new wiring harness. Any thoughts or suggestions?
