Sorry a little late on answering this. I just bought a used 2017 SE Premium. Yet it appears the original buyer didnt spring for an upgraded sound system. I have an 8 speaker system, that just sounds ok. Took it to a reputable custom car audio retailer/installer, and they did not advise in trying to replace the radio, since it is really only providing the source. Plus changing it could screw other integrated systems up. They provided recommendations for a new Amp, DSP, and subwoofer, that would make the things sound 1000% better. I just need to decide if I want to spend the $$.
