Hi so I just installed a sub in my 2012 Golf TDI. It has the tech package so the deck has navigation. I used a audiomobile line converter that I spliced into the back of the deck. I also used the negative from the deck but had to use another power wire because it was blowing the fuse. Now the vehicle does not lock, the trunk won't open, seat warmers don't work, headlights seem to be a little low, the seats don't recline back and the windshield sprayers don't spray. Just finished the install so not sure what else does not work. Any advice would be great. Thanks.
