I have been searching in vain to find information on a 2011 HHR, Stereo install? I have read that the HHR changed thru out the years with the electronics but why is it so hard to find a simple 2011 answer? I have the basic system with out all the whistles and bells, mine is so basic that I don't even have a Sub-Woofer, which I would like to add along with my Sony Model# CDX-C510
Can anyone help me?

(Edited your Model Year to 2011, we wish there had been 2012 HHR's but no such luck, GM can really be a party pooper!)843de

 

Well the first issue is that they stopped production in 2011, there are no 2012 HHR's so look up the 2011 for info

 

The folks at Crutchfield have a really good section on HHR installs, plus tech info, so give the link below a try...

Your Soooo right, I just hit the wrong number, oops sorry about that

 

No need to apologize Techman-10, occasional glitches in the "Brain to Fingertip Interface Module" occur.

Why only yesterday, I couldn't seem to snergle a complete gigglesnort without causing the spellchecker to have a breakle mentdown.

 

Well now that the typo has been addressed and corrected, dig into that link Mike posted and see just what you'll need to power up every Friday at 6:00 Queen's " We are the Champions " and every Monday at 6:00 pm , Twisted Sister's " We're not gonna take it!"
