I want to install a single din dvd deck in the storage box of my 04 TSX. I went to the dealer and they are asking for $120 for parts and 3hrs of service totalling $450 + tax.

I live in Canada. Is that reasonable? Can I have it installed for cheaper somewhere else.

 

That's way too expensive. Go to a stereo shop. Also get the Acura OEM mp3 attachment kit for like $75. It will make the install easier and you may even be able to do it yourself.
