Hi,

I'm working a little bit around traffic subscriptions in garmin and trying to find where are stored related data. Yes, I know that we can add/remove traffic subs directly in device with calculated key, but I want to discover how work with digital traffic (LMT-D devices) subs. After some "social" engineering with garmin helpline, helpline can not work with digital subs in other way than device return.
In case that I have some basic knowledge how TMC traffic works I've tried to find where are those subs stored. I've done these steps with (nuvi 150LMT):
- backup off all recognizable regions via update.txt to SD,
- add licence
- backup off all regions vi update.txt to SD
- only regions 13,41,91 have some differences
after observation of these diffs which are unreadable in easy way, I guess that there is some kind of filesystem.
Anyone have any suggestions / ideas?

all best
