Just to the left of the clock (but to the right of the 'source' button) you will see some icons (bluetooth, phone battery level, phone signal strength, etc.) Swipe down from that general area (it's a pain to hit the right spot.) You should get a list of notifications and one of them will say something like "Location sent from Honda-Link App" and you can click it to open it in the built-in GPS. Of course this assumes you have the touring model, I don't believe non-touring has the GPS (and therefore this feature.)
I will admit it doesn't always show up there right away, and sometimes it seems to never make it...
