ML320 Radio No 12v at plug

[topsyontop]

Hi I changed my battery and had to remove the radio to get the code, when refitting the radio it would not switch on, on investigation the constant 12volt feed is dead at the plug
I have checked all the fuses and all are ok

Any suggestions

Regards

Have you checked the fuses in the footwell?

Dis you actually pull the fuse out to check it? (under bonnet)
