I have a couple of questions that I have been searching for the answers too.

First does anybody know of a company that makes a Double Din factory Stereo replacement Kit??? I'm looking at installing a an alpine dvd player and screen in place of the factory radio.

Second for any of you who have replaced the factory stereo and have NAV. How did you get the NAV sound to work with your new head unit??? I have a couple ideas on how to do it and I'm also working with a local car stereo install shop on some of them. I just wanted to see if you guys have a quick and easy solution that doesn't cost much!

 

No, there is no kit available, you have to make it, but its definiely possible, here, check this one out we did not too long ago:

 

thats my set up minus the EQ but i have the factory navi is it posible to use the navi stereo controls with the new head units? being that honda/acura heads are alpine it all should plug right in correct?
