Just bought a 2008 550. While installing a booster amp for the subs(did this on 04 545-- big difference), I believe I blew the fuse for the main logic 7 amp. I looked at the fuse panel diagram-- talk about confusing! I could find nothing in the manual explaining the symbols used by BMW, some were obvious what they were for and some weren't(at least to me) . I did a search on the site and couldn't get anything. Can anybody tell me which fuse or fuses are for the logic7 amp? I checked the ones that showed the radio symbol.

Regards,
