I still have the factory am/fm/cd player headunit in my 09 HHR LS, I believe it's just the basic/non-premium setup it does have a front jack for mp3 player input. Well, I was just wondering if these headunits have rca outputs on the back to add amps/etc? I know they sell adapters/converters if it doesn't, but would like to know before I do any upgrades. Also, is there a thread on how to remove the headunit? Looks like the plastic around it has to come off 1st, but I don't want to ruin/break anything taking it apart! Any hidden screws, etc that I need to be aware of? Thanks for your help!
