question on the 08 nav

[n3.5guy]

I just recently got an 08 coupe with the navigation H/U, so I am very unfamilar with most of it. My question is does the navigation have RCA inputs, and secondly if not would it be easier to just get a different aftermarket head unit or is there something else I could do.

My objective is to put in an amp/sub deal. Any help would be appreciated.

No RCA inputs-- only the single aux input below the AC dials.

I highly recommend purchasing the Nav with the BOSE system. There is a thread in Audio/Video that explains how to tap into the BOSE amplifier in the back of the car to add an additional Amp and Subs.

I do have the bose system with the nav. So in order to do it right I would need to run a power wire separate to the one for the stock amp (for a separate aftermarket amp). Then just tap into the rear speaker wires in place of the RCA's and remote?
