+Custom Firmware
+===============
+
+For TomTom PNAs there are several inofficial firmwares. These allow you to run newer firmware versions on older devices.
+You can make the firmware believe it is on a different device to enable additional features. This is set by the file `config/model.txt`. The following values are possible:
+
+  * `ori` - doesn't emulate any other device, i.e. runs the normal firmware for your device
+  * `x20`
+  * `x30` - gray/orange look
+  * `x40`
+  * `x40light`
+  * `x40light2`
+  * `x40light3` - *One XL Live* features
+  * `x50` - Standard, all features (e.g. animations when opening and closing dialogs, "Eco"-planning mode)
+  * `xls` - fresh white/blue look, old icons
+  * `ttssdk`
+
+For my *One XL*, `x50` (blueish with animations) and `x30` (gray/orange look) looked beautiful but didn't get me any TTS voice output.
+I especially like the display of the lanes besides the next direction. I don't know why TomTom doesn't enable these features for all their devices. Very strange.
+`x40light` seems to be the native mode for the *One XL*. `xls` also works with TTS voices. [This posting](http://www.ipmart-forum.com/showpost.php?p=2542293&postcount=17) possibly explains
+why the LoquendoTTS voices don't work in all emulations other than `x40light`. But there is a *VocalizerTTS* system with a very limited set of languages available. It should work with these emulations.
+
+
+Additional applications
+=======================
+
+TomTom allows third party applications to be installed on their PNAs. If a developer has prepared a *TomTom HOME2* package, just unpack the files to your *TomTom HOME2*'s `Downloads` directory, usually located in:
+
+    C:\Documents and Settings\<username>\My Documents\TomTom\HOME\Downloads\complete
+
+Just create a new subdirectory and put the files in it. You can then install the application by going to *Add Traffic, Voices, Safety Cameras, etc.* → *Items on my computer* and
+clicking the **Add** button for the new items under the *Applications* category.
+
+Joghurts GPS-Site
+-----------------
+
+He has programmed *FuelControl*, a *Calculator* and a *Height* display. Download everything at http://gps.dg4sfw.de/.
+
+
+Delete Traffic Camera database
+------------------------------
+
+[pasternak.net](http://www.pasternak.net/joomla/content/view/53/73/) has an application which can delete all traffic camera POIs with one touch - useful if you get caught by the police.

+
+Bugs
+====
+
+Avoiding the Werner-Voß-Damm
+----------------------------
+
+Trying to navigate from Hoeppnerstraße, Berlin (Germany) to the General-Pape-Straße 1, the device calculates a 3km detour instead of sending you right through the Werner-Voß-Damm (some 100 meters).
+This happened to me on NavCore 9.014, 9.022, 9.024 and with maps Western\_and\_Central\_Europe\_2GB v830 and v840.

+
+
+Crashing showing a specific crossing
+------------------------------------
+
+  * **Preconditions:** Navigate from `N 52° 42.766', E 12° 35.623'` to `Humboldtallee, 14612 Falkensee` and have the "Hide map above speed" setting activated
+
+Approaching the round-about at `N 52° 42.134', E 12° 36.068'`, everything is fine. If you go above the "hide map"-speed, you'll see the roundabout, if you go below the speed, you'll see the map.
+
+After passing the roundabout, the map displays fine but as soon as you reach the speed where the device should show the next crossing, the device hangs and reboots.
+After it started up again and you're above the "hide map"-speed, it crashes and reboots again. The crossing which should show up is the one at `N 52° 31.744', E 13° 06.607'`.
+
+Tested with NavCore 9.014 and 9.024, maps 830 and 840. All combinations show the same behavior.

+Concat Transport Stream
+=======================
+
+Copy recording from the TSD drive to a FAT32 USB HDD.
+
+    cat movie.TS4 movie_*.TS4 > movie.ts
+
+:warning: Target drive needs to support large files >4GB
+
+
+Convert to MKV
+==============
+
+    avconv -i movie.ts -sn -vcodec copy -acodec copy movie.mkv
+
+If avconv aborts because of incomplete frames, use `-ss` and `-t` to seek a few seconds into the stream and stop a few seconds before the end.
+
+
+Rip recordings to DVD
+=====================
+
+    avconv -i movie.ts -target pal-dvd -b:v 8888k -vcodec mpeg2video -acodec copy -ac 6 -mbd rd -trellis 2 -cmp 2 -subcmp 2 -q:v 1 -r 25 -s 720x576 -aspect 16:9 -f vob -y movie.mpg
+
+
+  - cut and demux using *ProjectX* 
+    * if not yet set, set Presettings → Special → global PTS shift (in hours) to **auto**
+  - burn DVD using AVStoDVD
+
+Notes:
+
+  * it will use the best audio track (see avconv doc)
+  * bitrate 8888k can be reduced
+  * direct piping (`cat movie*.TS4 | avconv -i -`) doesn't work (in Windows)
+  * ProjectX doesn't like `avconv -g 100`
+  * without demuxing, AVStoDVD can't sync the tracks
