As far as I can see, the radio fuses are in 2 locations.
For LHD car,
Fuse no. 1 is 20A and located in the engine compartment fuse/relay box Right hand side near the windscreen.
If there is a group of 8 fuses, the radio1 is 3rd one down 20A.
Fuse no.2 is 10A and located in the drivers side kick panel fuse compartment.
If there are 3 columns of fuses, the radio2 fuse is the 10A at the bottom of the centre column.
I hope this is correct information.
Best of luck.
