Can anyone help me? I am trying to install a Pioneer deck in my 2003 Blazer. I have the Metra GMRC-01 unit connected, but my deck does not work at all. There is power going to the speaker on the GMRC-01, but the deck has no power at all. Anybody have any ideas as to why this is the case? Any help would be appreciated. Thanks!

I like to ground the HU's ground to the chassis of the car under the dash... posted_image

Did you hook up ignition to ignition, , 12v to 12v, and ground to ground?? Double check those.
