So i’ve got a q60 2015 and this car is practically the same as g37s: so has anyone gone through this??
i left my lights on and my battery died. at first i figured big whoopty do but then after jumping it, my audio doesn’t work.
Ive checked the audio fuse & it was burnt so i replaced it, nothing
Unplugged the terminals cause i read somewhere that can restart it instead of a radio code; yup nope.
Now i’m thinking the amp might be bad, some how some way. but i’m not sure.
Anyone else go through this or have any ideas?

 

I would guess you've got another blown fuse. Might be worth going through them checking for continuity on all the fuses.
