If I get a 2008 DVD/NAV model 25797978, what would I need to add to my current 6disk indash factory CD radio?

As I already have a portable NAV unit, I'd like to be able to get voice commands working and a rear camera added while retaining the stock look with a 25797978 unit.

I love the portability of the portable GPS I have, but the rear camera would be the main reason and DVDs a plus(so I dont have to lug around the portable dvd player as well).

I also don't mind buying aftermarket amps to get it working. Thanks for all help.

 

Let me know how that works out for you. No one seems to know how to program '08's. I have an LS also and can't get the Dual Play DVD/CD to work, low volume or not.
