011 Camry in-dash upgrade?
 

Can anybody steer me towards an in-dash upgrade for my base-model 011 Camry? My in-dash is just a single CD am/fm...I do like the fact that I can run my Droid into the head unit for my mp3 collection, and the speakers sound great straight from the factory, but I was thinking an upgraded head unit would have a sub-out channel I could use to put a bass tube with small amp in trunk to augment the thump and lows, and slao maybe would have a visual display of some sort...
Any ideas?
Thanks,
Tim
