There are pretty detailed photo's above that answer just about every question you just asked. The old DC011 had no BASS period. The DC012 has much better sound. There is a button to turn the BASS on/off. No EQ, just on or off. The knobs on the top adjust volume and fine tuning your radio. There is a Aux port on the front of the radio to plug in your MP3 player. If you wanted to charge your MP3 player you would have to have a non USB plug and plug it into the side of the radio. There is no dock, just a "nest" on top of the radio to hold your MP3 player. See photo above.
A few changes worth noting.
The roll cage is a lot more durable than the previous DC011. The DC012 radio is much heavier. The memory battery is a better a better battery rather than the quick dying AA batteries. The reception is slightly better, but not that much better than the DC011.
