It's also when they start updating the firmware in the other components outside of the infotainment unit. The likes of Obdeleven will tell you if it find an older version of a component firmware in the cars system by just having a record of what the highest value is found by people using the tool. Because there is a higher version in one unit of the car it might not work with a different release somewhere else in the unit. It's a distributed control system so if you started updating the firmware just because it says there is something newer, it can open a can of worms. Whilst the dealer has access to the update notes, the end user doesn't. It exercised @East Yorkshire Retrofits at one point that people were updating beyond what they should be. Probably why Vag took exception to people changing firmware other than by qualified staff given the amount of issues they had with the MQB Evo platform in the early days that have now been ironed out, so one is told. There will be these issue cars around that haven't been fixed where the owner has lived with the bug.
The popping and the clicking of the SOS isn't part of the infotainment system. It's when people start hunting down the firmware of the other control units and whether A works with B etc. It's that reprogramming that dealers get you to sign for, or some do, others say we need to. If you do DIY on this stuff then it can push it over the top.
All of this is different to updating the maps which isn't firmware but data for the navigation program to use.
