I should have done this years ago.. I started trial and error testing of which BaseCamp symbols will actually transfer and show up on a Nuvi 3597.. very tedious to do but here are the BaseCamp symbols that show up on the 3597.. House, City Hll, Bank, Restaurant, Camera, Airport, Lodging, Picnic Area, Pharmacy, Shopping Center, Live Theater, Bowling, Rest Room, Car, Amusement Park, Hospital, Information, Ski Resort..
