all of a sudden my head unit wouldn't turn on any more, so i used my volt meter and discovered there was no longer any juice at the wiring harness that used to connect to the stock bose head unit. i checked the fuse and that is ok, this one has me stumped and worried, don't want to have to go tearing into the dash looking for problem, any ideas would be greatly appreciated.

 

tear through the dash and look for problems
