I've got a 2011 x coupe with bose sound system and non-nav - I'll cut straight to the point - my radio doesn't work. Whenever I switch through radio stations, all I hear is static, and occasionally, I'll hear something coming through, but with very bad reception. I unplugged my antenna, and the issue didn't change at all - could it be that I need to replace my bose amp? If so, how would I go about doing that? Thanks
