Hey guys, I'm finishing up some interior modifications I've been working on over the past few days and figured i'd ask a few questions i've been meaning to ask for a while. The stuff I installed (which i absolutely recommend, they're awesome!) is this TaoTronics bluetooth adapter which I wired behind the dash into the stock Bose unit, this Ginsco hardwired dual USB port that i drilled a hole for under/in front of the e-brake, and this magnetic phone mount. I got everything wired up behind the dash finally.
So to wire the aux-out from the bluetooth unit into the stock radio, i found where the overhead dvd player audio lines from the RCA input go into the back of the head unit and spliced it in. It works great, but my only problem is that I have to push the little black button on the DVD player each time I start the car to get the head unit for the DVD-aux option to pop up. It isn't a huge deal, but I would really appreciate figuring out a way for that to be enabled when the car starts.
My other question is with the power. Currently, I have a disassembled standard dual usb cigarette lighter with a positive and negative lead soldered on, running to be spliced with the cigarette lighter wires behind the dash. I also have the Grinsco port wired into the same splice. (Side question, that isn't too heavy of a load is it?) I have the bluetooth system plugged into one of the behind the dash ports, and the other one is a dedicated QC 2.0 port that pops a usb-c cable out right beneath my phone mount. I'm really happy with the way everything turned out, but I wish all the components were switched and turned off when the car did. Is there a way to change the cigarette lighters from always on? I know some cars allow you to do this by changing the location of a fuse, but I couldn't find anything on the trailblazer. Thanks, Rob.
PS, sorry this is horribly formatted. It's late here and my brain is tired
Also, if anybody wants a guide to how I did any of this, just let me know. Here are some pictures of the setup:
