I’ve tried using it over the years but I never liked it because there was no information. So last night I looked at my local city and there is almost no information at all. I spent a few hours last night adding buildings and restaurants and removing incorrect items. It was actually kind of fun and therapeutic and I plan to do more of it tonight. My girlfriend thinks it’s dumb and I’m wasting my time because Google maps and Apple maps and Bing maps exists but she just doesn’t understand open source.

Edit: Apologies, I just realized this question is not Linux specific.

    There’s a list of ready-made providers of gmapsupp.img files.

    I’ve had the best luck with BBBike and OpenMapChest for getting pre-built map files.

    Basically you have to get one of these files with all the data you want in it and then stick it on your SD card on the GPS. (The GPS should mount like a thumb drive. If you already have a gmapsupp.img file on there, you might want to back it up in case things go sideways.) Some GPSes support multiple gmapsupp.img files, but a lot don’t. Here’s a thread on merging .img files.

    When I needed super fresh data, I’d download raw OSM data from Overpass and use mkgmap to build the gmapsupp.img.
