X2 to Oldblue's advice, and the non-presence of OnStar could mean your HHR is an ex "Fleet Vehicle". But to see exactly what audio system options you have, find the build tag on the inside of your glovebox, it's a 2" x 3" white or silver label covered with a list of three digit codes.
Here are the Audio RPO Codes...
UE0 Communication System - Vehicle, G.P.S. - Not Installed
UE1 Communication System - Vehicle, G.P.S. 1
UQ3 Speaker System - Enhanced Audio
US8 Radio - AM/FM Stereo, Seek/Scan, CD, Auto Tone, Clock, ETR, MP3, RDS
US9 Radio - AM/FM Stereo, Seek/Scan, RDS, Multiple Compact Disc, Auto Tone Control, Clock, ETR, MP3
UW5 Speaker System - 6, Base
U1C Radio - AM/FM Stereo, Seek/Scan, CD, Clock, ETR
U2K Digital Audio System - S-Band
It's your HHR's Birth Certificate, every option and optional variation has a code.

GM integrated a data bus system with the factory radio as a relay/hub or something like this starting around 2004. It apparently saved GM $$, but makes life more difficult for people trying to replace radios. I didn't get all the details, but basically without the factory radio installed, I wouldn't get indicator warning beeps for some sensors like if you leave the keys in the ignition, if you leave the lights on, if you don't put on your seatbelt, etc. The two options were to either run a power line for the ignition power to a spare fuse in the fuse box, or buy this fancy harness that had some little black box/circuit board thingy that replaces what you lost with the factory stereo. This is what I had to do in my GMC Savana, and it worked perfectly. Paid about $85 online

here's a link for the harness I used. Obviously you won't need the mounting hardware as this was for my Express, but this is the harness needed.
