Winston Wonderland

So I have a 2009 HHR eith Premium sound system (Pioneer Sub).
I bought an aftermarket Navi with Can Bus adapter, but the adapter doesnt do anything (it even didnt switched on)
So I bought a GM11 adapter from pacaudio.com
Now it does the chime the headunit turns on, but doesnt give any sounds...
I think the amplifier doesnt want to turn On! I tried the Pink and the green wire too but nothing
Should I bridge something? Or it wont work ever? The adapter and the radio both has amplifier turn on wires

please somebody give me any Tips!

Thank you all in advanced!
