Judging from comments on other posts (including yours) covering the routes to car topic, the common theme is that it is 'patchy' and is heavily dependent on the 'route details' successfully passing through Skoda's servers and thence OTA to the car. Software version 0276 was loaded onto our car to address the SOS call errors that kept occuring, but it also enabled OTA navigation map database and live traffic info to be received OTA, which on the previous software version did not happen. I would suggest therefore that in terms of your software version, you have one that does at least ensure that OTA communication to the car can take place (assuming such messages/data etc. are being sent from Skoda in the first place).
Dealers are meant to ensure your car has relevant software updates when they service it - again 'patchy' performance - ours has remained unchanged on 0276 through 3 services, and I have only seen one other forum poster noting they had had an update as part of a service without asking for it. Software updates take a long time and therefore I think dealers try to limit doing them to cases where they are needed to address a known fault, so as to not tie up workshop space. In my view, if everything else on your car is performing as it should (hardware excluded), then I'd leave well alone - if it ain't broke, don't fix it.
