ok, according to the workshop manual, it is a common fuse for the stereo, horn, brakelights, interior light, and a few others. try your horn, if it doesn't work, then it is the fuse in the fusebox. it says it is a 20amp, fuse number 2, it has a horn symbol. the other potential is number 15 which should have SERVICES written next to it. it is 10amp, and also controls the windows and reversing lights. again, try these, if they don't work, it is this fuse. other than that, the manual is a bit vague when it comes to the stereo.
on a slightly different note, are you aware that there is no switched live to the stereo? do a search on the gtv tech lounge and you will find loads of info. if you do not remedy this yopu will end up with a flat battery a lot........ best of luck.
