I downloaded and read the Kenwood DNX7100 manual and all I can say is WOW! I see you can get them just under $1000 shipped on eBay. It looks like it slaughters the D3, Z1, and Z2 in features. The only thing I don't really like is the GUI looks kind of cheap in screenshots I've seen, but I'm thinking it probably looks better in real life and even if it doesn't, I can get over it. I'm still left with a lot of questions though. Any DNX7100 owners know the answer? Is there a Kenwood forum somewhere?
The 2GB internal hard drive holds all the navigation data, presumably for all of North America, but I'm not sure. People say Garmin navigation is far superior to Pioneer, but I just wonder how this is possible when Pioneer needs 2 double-layer DVDs for North America which is over 15GB max capacity when the Kenwood only has 2GB? Does the Kenwood have fewer POIs? Are the maps less detailed? What kind of hard drive is this? Is it really a hard drive, or flash drive? Can it be upgraded? If upgraded, can you add more navigation data to it?
What does the bypass consist of on this, simply grounding the park brake wire?
The USB interface looks to be as good and flexible as the iPod interface. I see it supports categories like Artists, Albums, Genres, Songs. My iPod is 100% for car use and I hate iTunes so I don't use it (I use XPlay2 to sync files/folders). I would actually be more than fine with replacing the iPod with a 40 or 80GB 2.5" HD in a USB-powered enclosure. How well would a hard drive work with the Kenwood? Can it support Playlists? I didn't see that category in the screenshot in the manual. Is it as fast as an iPod? Is there a limit on the number of folders, MP3s, or overall capacity? I found no information about this in the manual, although I did see there exists an error message "USB Device Error!" whose definition is "The connected USB device is rated a current capacity higher than the allowable limit." Strangely, no mention at all in the manual what the limits may be.
Are there any drawbacks of the Kenwood compared to Pioneer?
