Help please. 12v socket fuse

In dire need of coffee and phone charge. 12v fused first thing this morning. Its a V Plate Volvo FH12. Any clues appreciated.

Change the fuse :unamused:

what was you using when it went you can change it but you need to fiind out what caused it ,if it was a kettle there usually 24v but not always

Any thing that makes heat uses a lot of energy,I hada 12v kettle but it was useless.It took 15 minutes to boil1 cup of water and the fuse blew regularly.

After a bit of googling found the fuse box and fuses alas more sinister than a fuse. Thanks

Sorry to jump on this but does anyone know which fuse in the MAN Tgx if for the multimedia system / radio

Thanks !
