Step 1. Install the free VW Pre Compiled Database located on the download section of this site to your PC:
https://free-speed-cam-updates.web2diz.net/
Step 2. Unzip/extract the files on your PC and copy the contents of the resulting folder onto a SD card.
( Important points to note: Only copy the contents of the main folder i.e. Do not copy the resulting extracted folder named Volkswagen PersonalPOI - just copy the contents that are displayed inside that folder which is a folder named PersonalPOI and a metainfo2.txt file. Delete the readme.txt file as well as that is unnecessary. Also further note that despite trying to use 2 different usb sticks unsuccessfully only an sd card would work for me. I used the sd card which contains my music files but remember to delete the copied files off afterwards as sometimes they may prevent your music from playing and they are no longer required as they have been copied to the internal memory of the Amundsen ).
Step 3. Using the "manage memory option" of the nav settings upgrade the software.
Step 4. In the "map" settings chose poi categories, scroll to the bottom and the newly added items should be displayed there. Tick these to activate them.
Step 5. In the "nav announcement" settings of the nav settings make sure that there is a tick in the "My POI" item. This enables an audible speedcam alert.
To sum up - it's pretty easy to do and it's free and there are monthly updates on the site. On the downside - I'm not sure how reliable and up to date the database is as I've already had to manually edit and remove an out of date camera from my location. IMO the audible alert is a bit feeble and can't be changed but it's better than nothing. I'm not too fussed on the camera icons either.
I hope this post is of help to others and I would like to thank the contributors of the other threads regarding this topic on this forum from whom I have gained my insight.
I have compiled my own version with my preferred choice of speedcam icons limited to UK fixed cameras and traffic light cameras using the VW database on the above site which I've attached below to share if anyone wants them. Remember to only copy the files as per the above instructions.
