Corsa c stereo not working

[ManikMuse]

Hi, i have a jvc KW-R400 head unit in my corsa c. About 6 weeks ago I had to jump start it because bird brain here left the interior light on all night!! Since then the stereo hasn't worked, no power getting to it. I've checked the fuses and all seem ok, and now I've run out of ideas. Can anyone help??

Thanks

Have you checked the fuse in the rear of the head unit?

Yeah I have. Well and truly stumped

You say no power getting to it - has that been checked with a meter ?

If there is 12v at the unit, have you tried a hard reset ?

there is nothing at the head unit. I must of missed something. When I looked in the main fuse box, there isn't a relay in number 12. I would assume that it's not needed or it has been bypassed.
