i have a 2003 acura tl type-s non-navi. i want to put a navigation system in it. how much do you think it will cost to install. I have the acura navi. system already. i just need to install it. and what else do i have to buy for the installation? please give me any information you guys know about this. thank you

 

First off, you're in the wrong forum.

Second, do you have the AC control unit in addition to the Navi screen and DVD/HD? The AC controls will run you $300.
You're gonna need to buy the navi dash, another $60.
Then you'll need all the wiring...I'm assuming you don't have that. I have no clue how much that will cost you.
Antenna assembly is another $100.......

See a pattern?
