Swap out Stereo/NAV unit: Is it on a fiber optic loop?

I have a 2004 SL55 and want to install another NAV unit with more features and Bluetooth.

Are the audio feeds to the BOSE system analog or fiber optic? This is my biggest concern. It should be pretty easy if they are analog. But if they are not..... I don't think it can be done without getting another amp.

Will there be any problems with interferance of other components if the MB head unit gets taken out?

sound on the SL is over the optical loop all the way to the amp. in fact all audio devices are on the loop and would need to be removed if you decided to replace things. additionally this may include even the speakers since bose likes to use 2 ohm drivers which dont work well with most aftermarket amplifiers.
