Update on mine:
Went in last Thursday for a speaker replacement due to popping/cracking noise - despite me telling him it was SOS module related he insisted it was faulty. Weirdly on the way to the dealer my car logged me in as it normally does, then logged me out, I then logged back in and it loaded settings then it logged me out again and since then I've not been able to log back in (I have only driven it three times since then so not had a chance really) however when I did try it just kept telling me it was unavailable or wrong or words to that affect.
Thing is until I am logged in I cant check if the speaker is now working as, because I am logged in as a guest its not tracking my position and accessing the internet anyway.
Strangely I don't get any messages on the dash when my speaker pops, I did notice the light goes off on the SOS module though. I did speak to a service manager and he told me that they have problems when cars go past electricity sub-stations causing the connection to drop, funny enough where mine drops every time I do drive past a sub-station.....
Car is going back in for a car seat that squeals like a pig whenever I sit on it.
