I spent literally all day on my "new" made in Finland 64GB Nokia N9 - my goal is to have it as my main/daily phone.

Biggest problem was how to get any sort of maps&directions running in 2020?

NOTE: I dont drive so i need maps just to know how to get from A to B, e.g. walking in a town i have never been in before. If anyone knows how to get GPS running in opera that would be amazing.

No clue how to get the nokia drive or maps running. so, sort of easy workaround:

Once you get Opera 12 on the N9, you can use https://www.mapsdirections.org on there for either directions in text form or also graphically presented. For best performance get to the settings of Opera 12, then got to advanced settings and switch to DESKTOP user agent.
