Answer to "Where are the GPS unit and its connections?"I can confirm the top right copper clip like piece is for the gps. It fell off when I took apart my phone to replace my cracked digitizer. I thought nothing of it and kept the copper piece in safe area . Weeks went by and I was wondering why my gps wasn't working. Then I decided to try to glue the piece back on and now my gps is working again. Took about 5 min to fix.
