Verify that your device does not share your contact book and texts over bluetooth (will break the infotainment built in “call X person” feature should you use that over your phones assistant for some reason)
Its usually in the bluetooth settings for a particular device paired to your phone
I felt the same however Organic Maps did have many businesses. And with Street Complete I can correct any errors when I visit.
It may simply be my area, but I so recommend organic maps over Osmand for business and POI lookups
