Depends on whether you have bose and/or onstar... that's gonna make a difference as for the amplification signals the RCA's connect to and probably explain the lack of audio
the important question is if your speaker grills say "Bose" on them or not...
cool ok, so... lemme
look this up again brb
GMOS 01 sound familiar?
whew ok there are a few for your truck listed on Metra, for the interface... which one did you use as a wire harness?
ok the 100 does it all and if you didn't get the one for your year... i saw something about cutting our resistors for non-amplified models, it would really be a deciding factor which interface you have although from the way it seems, you wouldn't need the use the RCA outputs unless you have an amplifier. I doubt that has much of anything to do with anything, the harness though? I mean, it's hard to say without knowing which one you're using... the aftermarket radio for those plugs into a unit that plugs into the trucks wire harness usually, and you should be able to solder/connect the speaker wires as mentioned in the manual, and if you have that, there should be a model number associated with it
it's more like you wouldn't use any of the speaker wires if you were using the RCA's actually, and that's for an amplified system
Nice, for there to be power and no sound it's gotta be something pretty straightforward
yeah I don't even see that one listed, not for the model of yours... http://www.metraonline.com/
this is the part that appars to be missing: http://www.metraonline.com/part/AX-ADXSVI
there are other versions, had there been OnStar or amplification... it's something that basically tricks the truck into thinking the stock radio is still there
I'm done for the night, it's most likely the harness... if you installed it yourself send me a picture, of the harness/wires; if not... I don't see how a shop would have let a customer take home a truck without a working upgrade
ish... yeah, I know that seems odd, domestic electrical systems are beyond complicated intentionally... I have never heard of any shop in my life who would let an install out that doesn't work, maybe it was just one of those days. If it "works" to the extent that you got power with ignition, there is a signal being sent from the source/head unit. If it's not making any sound, that's between the head unit and the truck... seeing as all the sound is is a wire to each speaker. There's something up with the harness, my best guess without any further information.
