On the Garmin 34xx units is a SID directory.
Mine is currently empty :-(

[Only registered and activated users can see links. ]
States:
Files are stored in 34xx .System/ SID and are traffic trends, instaSearch , instaAdresses and POIs and FastRouting related
So for City Navigator Australia & New Zealand NT 2013.20 - NAVTEQ the traffic trends file ("trafficTrendsv2" D323200.db) goes into SID folder or does it still go into the SQLite folder?

Also - what are the instaSearch , instaAdresses and POIs and FastRouting files (I know what they do but not the files to look for).
