I had a return at BestBuy, so, as I was already there, I explained to the Car Audio tech (turned out to be the same guy from before) about my problems taking the head unit out of my Protege for the last three or four days.
Long story short, he got it out . . . and celebration ensued. Truly, I have nothing bad to say about the guys at BestBuy. They've helped me out before, and, they always do an awesome job.
I was so ecstatic to have it out (FINALLY) that I did the AuxMod install right there in the parking lot - so, sorry, no pics. Like everyone before me has said, this thing works perfectly! There
is significant "hum" when my phone is charging without having a ground loop isolator in place (so yes, I will definitely have to install a GLI later), but, for now this = satisfaction.
When I go to install the GLI later, I'll take step by step pics then.
It turned out that the HU wouldn't come out because the bracket securing it to the center console on the passenger side was overextended, and, the Ford keys couldn't even make contact with it. We had to pry the trim (the faux carbon fiber and silver-painted plastic) away from the console (note: it won't move far with the HVAC controls connected), depress the bracket through the hole in the dash with a flat-head screwdriver (you'll see the hole I'm talking about if you detach the dash), slide a Ford key into the HU's appropriate holes to keep the bracket pressed flat against the side of the HU, then, finish removing the HU by attacking the other side with a Ford key as usual. ::frustrating:: It actually only required two Ford keys in the first two holes from the top. Save your money and only buy one set.
I ran the cords from the AuxMod > through the back of the console > through the gap in the back of the ashtray > and, into the storage pocket under the HVAC controls. I bought a male-to-female 3.5mm
Belkin extension cable to connect from the AuxMod behind the center console to a 6ft coiled male-to-male Belkin 3.5mm cable which runs from just through the back of the ashtray into the storage pocket. So, from the cabin, only the 6ft cable is accessible, and it stays tightly-coiled in the storage pocket when not used. It doesn't look stock exactly, but it is convenient and somewhat stealthy.
