srock HU replacement ....

[Jarhead767]

for a 2003 coupe with Premium Bose system. What are most of the folks going with? Is it a straight install or are you modifying anything?

I do have the stock navi as well .... I am anticipating space issues ... true?

I would also like assistance with this. My stock cd changer is starting to give me some minor issues, and I'd like an idea of how much money I have to save up before they become BIG ones. Also, does anyone know if there is a way to upgrade the map software for the GPS?

The climate controls and HU controls are on the same circuit board behind the dash, so you need to buy the kit that gets you new climate controls. You will also need to buy a new console piece (the aluminum trim) to fit an aftermarket HU. everythingg35.com used to sell these i think for like $350 (obviously most of it being the climate controls). But with the new trim piece, that'll put you at a double DIN size since the stock opening is to small for any aftermarket HU. So you could go with one with a screen or you could get crafty and put a single DIN sized HU in there with something else, like an equalizer. Personally I would go with Alpine or Pioneer. As for GPS nav I am of no help.
