So far I rather like my 2011 Sorento that I just bought. However, the factory stereo is terrible. Playing audio through the auxiliary or Bluetooth functions requires turning the volume all the way up to get anything resembling decent sound, even with the device volume cranked all the way up as well. When I switch to the radio the volume seems okay, so I'm fairly sure the speakers aren't really at fault. Plus the steering controls are pretty much useless for the factory Bluetooth. I don't want to blow a bunch of money on a big new stereo, but some single din aftermarket stereos I've looked at seem like they'd do the trick. Has anyone had any luck installing single din stereos in this model? If so, did it help with the volume? Did the steering wheel controls work after installing? And by the end did the smaller sized stereo get installed without looking tacky where the bigger factory one had been? I can't find pictures with single dins anywhere online.
