I'm still looking for someone that has installed a orginal Double Din Nav./DVD radio in a HHR??I'm seeing alot of otions on this Avalance,Suburban,Silverado,Yukon,Denali,Tahoe Something out of these has got to work.Someone has to of installed a GM radio in there car.I have had several tell me that have installed a after market one but would rather not go that route.

 

My only suggestion is that if you find one, make sure to get the VIN for the vehicle that it came out of and be ready to pay the dealer big bucks to reprogram it. I still have a 6 disc changer and XM sitting on my workbench for about three years because I wouldn't pay the dealer $100 to reprogram it.

 

Careful CAREFUL! The hhr is an 11 bit lan; the other GM vehicles you mentioned are all 29 bit lan. Therefore anything for them would be incompatible with an hhr. Best bet is to get an Axxess gmos-lan-04 which will enable you to install an after-market unit such as Pioneer avic-x920bt, Z120BT or Kenwood.
The GMOS-LAN04 is for cars with onstar and amplified sound. There are other models for non-amped systems w/o onstar. You will also nedd a steering wheel control adapter is your car is so equipped. Axxess or Pac make them
Most of the after market nav units seem to include bluetooth and dvd players.
Prices range from $650 (920-bt) to 1300 or more for z120bt or Kenwood.
Hope this helps.

 

I agree with the dr. I don't think a GM NAV radio from another model is going to work.

 

it will be less of a pain in the butt to go with double din after market.
Take a look at the Alpine ixa-w404 with the optional NAV. It looks great in the HHR. I love mine. You can pick them up pretty cheap online these days, check Amazon.

 

How about this one? 2DIN, NAV, DVD, Digital TV Tuner !
