An update on this situation. My car went for some remedy work to Seat Garage and i also pointed out again the
issue.
Information from garage below:
We are still having issues with the sos system and the infortainment screen issue.
These faults at present are not fixable at present as per bulletin from Seat UK.
Please can I confirm that this issue is not an action by Caffyns Tunbridge Wells as its SEAT uk that cannot supply us with a fix.
I'm using their courtesy car seat leon 21 plate and don't have any issues with
the multimedia unit fitted in this car is 5FA035862D firmware 1803
I'm honestly considering take this issue to motor ombudsman as this system isn't fit for purpose and just bugging me all that time while driving. Obviously after error I'm loosing my Internet service and traffic updates doesn't work as it relays on connection to Internet.
