'06 2.5L NB. So, I got the removal tools to get the radio out to find the ser. no. Now I can't get it to lock back in! I took the tools out and popped the spring clips out and tried to push back in. Can get it within 1/16th but does not want 'snap in'. Pushing as hard as I can! Guessing in part the wiring harness is resisting....super hard to pull out initially. Do I need a bigger hammer?
