2005 Powerwagon with Infinity sound system has problem with volume ****. I can control volume from steering wheel controls but if I try to adjust volume with **** on stereo volume goes all over in that adjust up and maybe volume will go up or down at random. Any ideas?

 

That's in your head unit unfortunately, sometimes those factory ***** just mess up internally (assuming you have a factory head unit).

 

Radio was bad, also had a parasitic draw that would drain in battery in 3-4 days if not driven. Replaced radio with one from OEM Radio, plug and play. All is good now .
