I just successfully updated all my Kenwood 9260BT maps to 2012.20, this included all of Europe, 3D buildings and photo real junctions and so I thought I'd share. This is what I did:
The whole of Europe file is now too big to fit on the internal 4GB memory of the Kenwood because of all the other files (Voice, 3d buildings, photoreal junctions etc), so I download the Original Mapsource file from the Garmin Maps forum and created two maps which the Kenwood sees as one.
To do this, I opened the map in Mapsource v 6.15.7 (only this version lets you unlock the maps easily) and used the Jetmouse Keygen to unlock the maps for my unit.
Using the mapsource map selecting tool, I selected all the maps for Western Europe Countries (making sure I hadn't missed any parts) and sent them to the hard disk. This created a directory on the local drive called c:\Garmin and placed a gmapsupp.img and a gmapsupp.unl file in it.
Then I went to that directory and renamed those two files to gmapprom.img and gmapprom.unl
Then in Mapsource, I selected all Western Europe maps in the list on the left bar by clicking on one of them and pressing ctrl+a. Then using the map tool, I zoomed out of the map and selected everything on the map screen.
Then I pressed the delete key. Because the maps I originally sent to the USB stick were still selected, I'd deleted only those maps already sent, just leaving any remaining maps, so basically just leaving Eastern Europe.
Then I sent these to the hard disk again. This created two new files in the c:\garmin directory called gmapsupp.img and gmapsupp.unl.
So now I have 4 files, two unlock files and two map image files Western Europe at 1.9 gb and Eastern Europe at 470 mb
Next I downloaded the 3dimage files from the Garmin Map forum and the photo real junction file (JCV). The JCV file you need is the last one in the first post (557 mb) The other smaller files work but are of a lower resolution for smaller screen devices.
Then I plugged my laptop into the mini usb socket on the unit and backed up the internal memory of the Kenwood (I leave a lead plugged into that accessable from my glovebox which makes things easier)
Next I deleted the the Gmapprom files, the 3dimage file and the JCV file from the Kenwood and copied the replacements over into the relevent directories, remembering to include the gmapprom.unl file in the same directory as the image file.
The two remaining gmapsupp files I copied into a directory called "garmin" on an SD card and placed it in the Kenwood SD slot.
Reset the unit and bingo! All maps and images updated to 2012.2. The Kenwood even allows seemless navigation between the internal Western Europe and the external Eastern Europe maps, should you need it.
I also finally worked out how pre-plan routes in Mapsource and transfer them to the Kenwood! - I'll write how in another post later on...

Just in case it's useful for someone, I uploaded a bundle of the files I used to my RS account.
2012.2 Western Europe, Eastern Europe, 3d Images, Junction View, Mapsource 6.15.7, Keygen 1.5. (Single 2.6GB download you'll need an RS account to download)
Take a look to the folder structure of your navi, i know that DNX9280BT can support ASR and trafficTrends too, maybe can be supported by your model, if you have the"ASR" and "SQlite" folders you can update this files.
This seems to be a very helpful thread although I am not sure where to start. I have a Kenwood 5260BT with an SD card update option. I am a noob so I really need some direction.
How did you access the file system? Did you connect to the device via the USB input at the back? Where did you download the maps that are compatible with Kenwood Garmin units?
I tried to download your file from Rapidshare but its not there anymore.
Did you install speed cams as well?
Also, though I would mention. The user interface seems quite clunky. I am unable to find addresses without a postcode. Actually I can find them, but not all but its challenging. There are certain things I would rather change. I am coming from a TOMTOM system you see.
Any help is much appreciated.
also, just want to know if you got lane assist with the new maps? I really want that feature

It's a nice how-to for updating DNX-Devices. please, can you have a look to my post and try to answer me (DNX 9280 BT Voice Control fails with CN2012.20).

Thanx Wiz for the tip. The 2 maps are now visible in the menu under one checkbox so they obviously work well together.
When I was using a map on an sd card I had a problem with the traffic not being calculated in the route although it was visible on the trafficmap . That works fine now.
There is only one problem left and you didn't mention it in your "manual": the speach recognition (ASR) doesn't work. So you can't enter adresses with your voice. Does it work for you?
Did you copy over the new ASR files? They will have been updated.
