If you are looking for sound quality and a head unit that does it all, this should be your choice. It will automatically determine equalizer settings, time alignment and crossover set points and slopes. It will handle up to three separate amplifiers. It also has two USB outs and one AUX out, so it can be used in almost any configuration. Great unit for sound quality. It fits nicely in the Grand. Touchscreen navigation is all that is missing, and that is hard to come by in a DIN 1.5, but you are making a trade off for quality with this unit.
