I was tempted when I saw the specs on the Kenwood DNX9960, but once they put the manual up, and their "Advanced" voice recognition works just like the 9140, I couldn't buy my Z110 fast enough.
The DNX9960 requires that you be staring at the screen to use the voice recognition with your iPod. Instead of saying "Play Artist Green Day" like the Pioneers, you have to say "Search Artist G" then look at the screen and say "Next Page" (like 8 per page) until the one you want is on screen, then say "Line 4".
The Garmin nav with the lifetime subscription to NavTraffic would have been cool, but I listen to music about 200x more than I use navigation anyway, so I'll take the Z110 for half the price, thank you very much.
