Had 1940 installed during dealer service the other week, now getting almost continual SOS and Travel Assist errors with a ding everytime it occurs, which is when I assume it's losing the internal SIM connection (which it obviously needs for the SOS, but does the Travel Assist use the SIM, or do they share a module?).
Had restarts, sound pops(or even no sound at all), SOS and travel assists errors occur randomly on 1890.
Took to the dealer, was told restart issues fixed with update (updated to 1940)
Restart issues gone.
As for SOS and travel errors I was told it was known issue in steering wheel and fix is to replace it.
(after that noticed if I adjust wheel up or down errors would disappear, also noticed pattern errors showing up when moving slowly and maneuvering in parking)
Currently 3 days with replacement wheel and no errors pop up for now
