Where is the fuse for cigar lighter on my 2007 Mondeo edge?

Dear Sir

The cigar lighter on my 2007 Mondeo Edge is not working as I use this for my sat nav, I have looked in the handbook and it shows a cigar lighter symble being the reference of the fuse, but this symble is not shown in either the main or auxillery fuse box. Can you tell me which fuse relats to my problem.

Thanks
