How do I get TomTom Home to recognize my Renault Carminat SD card?

I am trying to update the SD card from my Renault Carminat and in TomTom Home is just says "No device connected" even though the SD card is inserted and recognised in windows. I have used the SD card on my laptop and also an external SD caddy on 2 different PCs.
