Easiest and simplest way to bypass the 03 Envoy SLT's oh so joyous and not in anyway frustarting bose premium sound stereo system, if any at all. Is there a way to possibly just modify the bose unit with an aux jack even or am I stuck with no possible choice other than to buy that ridiculously overpriced wiring harness. (Just saying with all the smart people in this world there has got to be someone out there that has found a way to possibly hardwire directly into the factory harness)_not a car guy or electrician or anything like that just a guy that hates bose right now_
