Terrible stuff:
App mode doesn't work at all with my iPhone 5s, and I've hooked it up with the recommended Pioneer Cables. A huge, hot mess, all of it. Waze doesn't run at all, what apps I can get to run boot out of app mode on either the iPhone or 7000 NEX at apparently random points.
Siri eyes free doesn't work. It takes my command, gives a beep, then provides 3 seconds of hissing static noise.
You cannot set the zoom level on the map. It defaults back to whatever zoom it had when hard power was last applied to the head unit (don't ask how I figure that out). I've spent a few hours trying to get the map to hold a given zoom setting, simply can't find a way to do this. Nav overall is bad on this unit, nothing at all like the current Garmin and Tomtoms, of which I own several.
Dimmer mode is confusing as hell. Very confusing. I finally found an item buried deep in the manual that when the illumination lead is triggered (by your lights), that the screen has a separate set of settings. Fair enough, but the default is the same as the day mode! Terrible for those unfamiliar! Also, the dimmer only adjusts the screen, not the LED lights on the buttons. You can dim these separately, but then they stay dim in bright light. These lights should also switch with day/night mode.
Parking brake override DOES NOT WORK. Unlike the 4000NEX (without Nav), my unit figured out after about 5 miles that it was moving, even with a relay-installed parking brake bypass. After this point, it simply wouldn't allow many functions to be accessed unless the speed was below some low point (around 5mph or so).
Most modes have huge fonts with limited characters on screen and scroll the album/artist/title names. I hate this! This unit has a WXGA display; please, please, please just use a smaller font and show the whole damn title/artist/album name. This is really annoying with Sirius as well.
No animated background screens or wallpapers with the 7000NEX (this was shown in the demo video of the 8000NEX).
No album art over bluetooth (there is album art via USB).
No ipod connectivity in app mode (using digital AV connection as recommended.) You have to run an app on your phone, and it's a hot mess like above. Randomly boots out, required multiple confirmations on both head unit and iPhone, etc.
SC card files are organized by Artist/Album/Genre. However, when you selected an album, it plays tracks in alphabetical order! Completely unacceptable! They only way to play tracks in track-order is to go into the file system itself and find your album that way. If you search by "tag", it only plays in alphabetic order.
That's a partial list.
Frankly, hardware is ok. Software is incomplete, very buggy. This unit is NOT ready for primetime. The joys of being an early adopter.
