After owning the 100d for 4 years all I have to say is yuck!!!!!!!
You could not pay me to take another one, nope.
Lets see the dsp made the radio sound like it was at the bottom of a metal well.
Very low audio output from the speakers.
PITA menu system, worse than the 706.
The one thing I did like about it is that I payed 475$ for it and sold it for 625$.
