I did the software update and purchased maps & speed cameras at the same time on my laptop for the Carminat TomTom (Renault Scenic 2011), I inserted the SD card back into the car following the correct instructions. When inserting the SD card back into the car I got an egg timer, then a green screen with picture of a sat nat with a red cross with a hand and an arrow to remove the SD card. I have done all the trouble shooting and still does not work. Wednesday (27/03/19) I took the car to the Renault dealership for a diagnostics (£108.00) to be told I need a new Sat Nav (£778.28+ VAT) and a new SD Card ((£122.04+ VAT) and then on top of that would also be labour. TomTom will not take responsibility and Renault case handler will not take my calls. Has anyone else had this very expensive problem from the free update?
