Yep avenza needs no phone coverage. the $19.95 a year well worth it, and a huge library of downloads covers all of US much of Canada and the baja 1000 trails. Lotta utube tutorials on use and helped a lot, tried on-x free trail and maybe the paid for was better just did not work well for me. Gaia good also.Avenza user here. Was a learning curve for me but like it now. Using free version.
I don't think it'll come with everything, but at least in Alberta, it's got major ones on it. Comes with all North America installed. Added bonus, it's essentially the same as the zumo xt, so you can use it on a motorcycle as well if you do that. Has road maps installed too.Does it come set up with ontario trails
