Ok so my friend well she has a 07 honda civic SI, and I was going to help her hook up her subs from her old car into this one. But this one comes with the built in navigation system like in the dash, here is a kinda picture of it

How would I go about getting this one out, to get to the RCA's in the back so I can finish the installation.

 

If it is an oem navi....it may or may not have rca outputs.....so i would do some research on the oem deck before i went out and ripped it out of the car....

 

I would assume that it does. Many OEM decks are coming with them now. I would search some Honda forums on it. Im sure its been done. I can see if I can dig anything up at work also
