I have a 2012 XC70 which needed the HU upgrade to allow USB map uploading. Volvo were to charge £60 for the software upgrade but it turned out that the HU would not accept the upgrade. The dealer did not know why so he logged the matter as a faulty HU and, since the car was at the time covered by the Selekt warranty extension, the HU was replaced free of charge and since the HU had to have the latest software, that was uploaded fee of charge and since the Sensus needed a map file, that was uploaded free of charge by the dealer, so I didn't have to do it. However if you have the same problem as I did, the HU will cost you £350 so best hope that the £60 upgrade takes without problem and that you can then upload the free maps yourself without problems.
