We have had the 1896 Software Update applied recently to our Leon FR 150 (delivered in November 2020) and have noticed a definite improvement over and above the 1672 software previously installed. Yes, it does a complete reset necessitating the re-registering of the car profiles etc but a small price to pay if things are better in terms of SOS errors etc. One thing which we are liaising with SEAT on is the reset (loss) of all of the map updates previously applied and we have encountered a few sat nav issues since the update. We just don't know if this is down to the 1896 upgrade itself or the older 19.7 map data that our car now has.
