What about DSP systems? They never mention that. I know the current Hualingan and Dynavin do not support them.

I think what they are doing to this unit is very similar to how cell phone companies will add their own features to phones. These guys are taking a Hualingan and enhancing it. I am glad they choose the Hualingan as it has the larger screen and looks better IMHO.

It is a shame that these units physically look like factory navigation. I mean, really, factory nav looks like an old fashion TV with two knobs or even worse, an etch-a-sketch. I think these would look better if they replaced the knobs with buttons.

Finally, my hope is that they do support DSP. Meaning, I can get rid of the MID\Business CD and the DSP amp still turns on.
