[2013 S60] Delete phone contacts

[s2zeller]

OK, I'm dumb.

I accidentally added my contacts to the onboard list, and now I'd like to delete them. There are some other phones I'd like to delete as well. This is the base infotainment system (I think... don't know if more were offered for 2013 or not)

I feel like I must be using the wrong words to search, as this seems like a fairly straightforward thing to want to do. I did RTFM and couldn't find anything there either.
