Recently installed dash cam and had tap a fuse to get power for it. Everything works except I somehow screwed up and my radio volume knob doesn't work. Everything is fine except no audio from the radio - despite the fact that the radio itself gets power/lights up and all functions work properly including GPS etc.
Where should I look first? I checked all the fuses and they all seem to be fine.

Do you have the harman/kardon LOGIC 7 sound system? If so you need to check the power going to it. It is located in the back where you normal find the spare.

Correct, steering wheel volume doesn't work either.
Yes to HKardon. Thanks for the tip, I'll check that on a warmer day ;)

It's entirely possible for a fuse to look ok at a glance but not be electrically viable. However given your project to date I would more suspect a connector is not fully seated or worst case a broken pin/wire.
