Just like bonesninja said..... this unit has THE MOST features of any unit I have seen.... the only 2 down sides I can see to the unit, is:
1) Basic display - can't Alpine jazz things up? Look at the 980!
2) If you have a large collection of music (I have a 160gb ipod with over 14,000 songs, and over 1,600 artist), when I hit the 2nd preset, it jumps to the C's.... so the jumps are large... this is where the iDA comes into play... but nothing has as many features / control ...
3) the controls are awkward.... I guess one can get use to them.....
This is the most likely unit to go into my car... oh, and the parametric EQ, has presets, how sweet is that? Even the cross over has presets!
