HI there. On my 2013 S80 I used to update the maps using Volvo discs and they did require an activation code. In summer 2016 I had the software update done to allow loading maps from a USB drive using data downloaded from the Volvo website. I have done that twice now and both times an activation code was not required. The car recognises the map data on the USB drive and starts loading automatically. Yours being a 2013 car I would have thought the same applies. I never did try using a USB stick before having the software updated because all the advice was that it would not work.
