I sure hope my Garmin works. I was planning to use it since the cell coverage/costs are so high.
Check your country lists now. You should be able to change the country to Canada. On our list if countries, Canada was not an option. Ours is about 10 years old and DH keeps saying he needs to update it. We ended up setting ours to the bridge, then used our smartphone after that for directions. I should have printed directions... and checked the ciunties in advance.
We went ti Belle River, Ontario a few years ago to visit DH mom gravesite but neither of us remember if GPS worked. I think not because we did stop at the local police station to ask directions to the cemetery. It was just a short visit while we were in Detroit visiting other relatives.
