Since when did C1 have maps?
If you have LR up-to-date, Map will still work. Also, Adobe haven't done anything here. It's Google who changed the API and Adobe aren't going back to update earlier versions of LR.
Even if you don't want to subscribe, you can still use the GPS data in LR. Alt/Opt click the arrow to the right of the GPS data - that opens Google Maps. Alt/Opt Shift should open another map application - last time I looked it was Yahoo but it might be OpenStreetMap.
