Does a Stealership ever do anything for free?If so, does this cost money for a dealer to do that?
As far as aftermarket deck, you would have to replace everything, because after the deck it goes into the amps via fiber optics. So replacing a deck with an aftermarket deck is not something many on here have attempted. Although I have seen some tear the dash completely apart and run a deck as the "Aux" off of the main stereo.
And I would love to see your fix for the cup holder. I snapped mine off 2 years ago and dont feel its worth $80+ dollars plus my labor to fix it.
