How to reset symphony 2 stereo (with BOSE)

Basically i'm a total twunt - following on from this thread (http://www.audi-sport.net/vb/showthread.php?t=34010) I was trying to fit my aftermarket sub an amp, but i stupidly wired in the +12v and earth the wrong way round, I heard some click and now the stearo won't turn on period.

I'm guessing (hoping) i've tripped something, does anyone know how to reset the stearo or any help/advice would be appreciated, seriously hoping I haven't balls up my stearo.

Found the problem, looking though the audi manual/book/thing that came with the car, there's a fuse for the radio in the normal fuse box, just checked it and it's gone, will replace it in the morning, but it's a big relef that it's nothing serious (well, still need to replace the fuse, but i have faith that's the problem).

Will teach me to rush things to try and get them done before going out - I should have just left it until tomorrow when there was daylight.

Sorry for my panic post, I was going to delete this, but though it might be useful just incase anyone does the same thing as me
