I have a '16 Sonata hybrid SE and have consider upgrading. Replacing the head unit makes me a little hesitant. The backup camera and steering wheel controlling the sound could be lost? I have seen aftermarket systems that can do all of that, plus Navigation. New door speakers would be the cheapest way first if I want to leave the present radio installed. AM and FM sound quality is lousy and XM is fair. Has anyone upgraded their system? I just want better sound quality. Not something you hear 3 blocks away. BTW, Crutchfield says OEM speakers are limited to 30 watts and are 2 ohm.
