VERY confused. I took my 2013 S60 RD in today for the 50 K service, and mentioned that I had issues with my iPhone X bluetooth connection and needed the update to SENSUS Navi so that I could upgrade the map via USB thumb drive. When I got the bill back, I noticed that I had "complimentary software updates", but was charged $80 for "software updates". When I asked what the difference was, nobody could explain it any better than "they're different...".
What's the difference, and, how can I tell? Do some dealerships do all updates for free (I know some are cheaper than others for the same items)?
