I work at an audio shop in the uk, and i hav a booking for the import (so US version) of this car.
I hve never come accross this car before so need some advice on how to remove the stereo, its the pioneer double din size touh screen stereo.
Please let me know ASAP

 

For the HHR here is how to remove the stock unit so it should help. This thread is from another site that has some great info

I just replaced my stock radio, and from starting to remove the waterfall to reinstalling it took all of 15 minutes, not counting the prep work such as soldering up the wiring harnesses.

 

Mr. Moderator, would it be a good idea to make this thread a sticky or what? I really needed a quick overview of how to remove the stock radio in my brand new 2009 HHR and it took a bit to find any step-by-step instuctions on how to do so.
