Hi Mike. Following on from your informative message earlier, I have good news. I got through to Renault via WhatsApp yesterday, explaining that I couldn't update anything through the R-Link Store etc etc.
They got back to me today saying that due to changes in International trading laws after Brexit, Renault haven't yet been able to supply customers in the UK with a store that allows us to update our R-Link 2 devices, and that there was no indication of when that store will open. So, like you, as a goodwill gesture, they are going to update my system for a year, free of charge. A result!
Many thanks again Mike, for replying to my original question. Really, really useful.
