I have Google offline maps downloaded for areas I end up in just in this case. Gotta do traffic rerouting the old fashioned way though.
Or have an old-school GPS map thingy in your glovebox.
(Also have kiwix and a whole archive of Wikipedia on my phone).
I wonder if meshtastic communicators sales took off during this. How’s LoRa traffic these days?
Thankfully I’m in Canada where it’s not impossible to end up in the sticks with no service.
Chewing through your handful of gigabytes/month of data wasn’t hard. Only in the past year or so have double digit gigabyte/month data plans become cost-effective.
And our roaming prices are extortionate, so for jaunts over the border (or internationally), I’ll sometimes go “naked”.
You click a few buttons to download OSM tiles and then it does routing. The latest OSM even has a decent amount of stores, restaurants, etc., listed.
Do they? I know there are a lot of old units out there but I figure people would have tossed them.
At least I’ve found Waze has been pretty good at starting off with wifi and loading the map of the whole journey after coverage was lost with some resilience for stops/detours.
But even if it doesn’t, there are a ton of offline map apps that use OpenStreetMap data.
You can also install Organic Maps on your phone.
