Fuses for car radio / octavia

Hi!

I have Octavia, year 2002, 1.9TD.

I have problems connecting car radio, and I guess something is wrong with fuses. (two different radios were tried).

My manual says:

fuse nr. 42 - 25A (fuse was blown, funnily, 15A not 25A as in the manual - it worked until now).

fuse nr. 57 - 15A

Here comes a problem... I can find fuses from 1 to 43 (in a side panel), but... where are fuses from 44 to 59?!?? It doesn't say anything in the manual about the location...

Thanks for help,

Regards,

M.
