Got my truck back from the dealer today and I would be lying if I wasn't very upset. Talked to the advisor and he said it was all done so I signed the paper, got my keys and left. From the second I pressed play there was absolutely no difference in sound volume and quality, upon further inspection of the receipt they stated that the TSB didn't apply to my truck, which is completely false. Fed up with my dealer, they should've called my and told me "this TSB doesn't apply to your truck," not keep it for three hours and do absolutely nothing to it.
P.S. They also ordered the repair parts for the hood fluttering, (I know there is a TSB out for this, but my hood doesn't flutter) if they so much as touch my hood when I take it in to get this straightened out, I will be furious.
