fuses in 1987 vanden plas

Hi,I just got a 1987 jaguar vanden plas,v12.It is a pretty nice machine,but has a few glitches.The power roof wont go,the power antenna works,but the radio does not power up,and a few others.I was wondering where the fuses are for the power roof,and radio.I looked in both holders but none are marked for them.Thanks.:confused:
