Ok. I found another guide on importing the POIs. Was also in German. This seems to be more straightforward. I removed the unnecessary details.
I have the gpx file of the speed cameras in oz (from Garmin), ready to put into the SD card. However, I'm not able to upload the file here. If anyone wants it, pm me.
The youtube link below shows in detail what you need to do prior to importing into COMAND albeit in German.
I have not tried this myself as I have yet to receive my car. But many many forums have people saying that they have been using this method and worked for them in Europe and UK.
Please do not blame me if anything bad happens...hehehe...If anyone is kind enough to try it out, let us know how it entails.
The installation:
Create a folder named "PersonalPOI" on an SD card
Store database there
Insert SD card into the Comand
Press the "Navi" -
Select "Navigation" menu bar at the top
Select sub-item "Personal POIs"
-The data will now be imported (lasting a few minutes).
Then, under "Navigation" / "Personal POIs" on demand optical / acoustic
Enable highlighting!
Important:
SD card must remain in the Comand it.
-Due to the large database, it may take about 5 minutes are the speed cameras are loaded for the first time.
Hints:
NTG-1 version 4.5 can display the speed camera visual only and only to a map scale of 200m
-As of version 2 can be up to a map scale of 1000m displayed visually Blitzer.Furthermore, you can also hear a warning before this (press "Navi", select Top menu bar, etc.)
