       | Osmand(fDroid) + brouter
       | 
       | Best offline navigation there is. You can even customize your
       | navigation profiles.

         | Too bad that using brouter with osmand is so complicated.

           | It is, but brouter's navigation is really much better. Just
           | yesterday, I was in a relatively unfamiliar, small (european)
           | city which I needed to cross. Organic Maps was sending me
           | trough small streets I would have shared with cars. I fired
           | up OSMAnd + Brouter to compare, and ended up picking the
           | latter: it sent me trough bike/bus-only roads, then a park,
           | to reach a dedicated bike lane along the river, far from any
           | traffic. The trip was a pleasure, though maybe a few percent
           | longer.

         | The nice thing about real GPSr units and things like Garmin
         | watches is that they (depending on the model) can last a week
         | to even weeks. E.g., if you use a GPSmap 67s for 8 hours per
         | day, it lasts 3 weeks. In the older units you can even put AA
         | batteries.
         | 
         | Cycling with a phone with the screen on and at full brightness
         | (which is what you need on a sunny day), a phone will last a
         | few hours at most. The magic of good GPSr units is that they
         | use a transflective display, the sun is your 'backlight'. (And
         | of course using something more akin to a microcontroller than a
         | smartphone SoC.)
         | 
         | Also, in contrast to smartphones, these things are really
         | rugged. Like last year I was cycling through the alps and
         | accidentally dropped my GPSmap at ~30km/h (without a case or
         | protection, who puts them on a GPSr?). It only has some
         | scratches.

         | It is really good, and Brouter-web is really useful too.
         | 
         | However, that combo is a battery hog. For some reason, OSMAnd
         | drains a lot more battery when using it in guidance mode with
         | Brouter, even though routing is much faster than with the
         | built-in algorithm.
         | 
         | I heard that Locus maps has a much better brouter integration,
         | though it is unfortunately closed-source: battery-efficient,
         | automatic brouter detection, profile selection from within the
         | app.
         | 
         | I also wish the brouter app would get a fresh coat of paint (a
         | UI redesign), but that is secondary.

       | I have a waterproof Garmin Nuvi GPS that will directly accept
       | OpenStreetMap data on micro-SD card. It is in bicycle mode and
       | running on a DC-DC converter from my e-bike pack. I am quite
       | satisfied with it despite being 20 years old. The external
       | storage and well defined format have saved it from becoming
       | e-waste.

         | Garmin is really good when it comes to open maps. I can still
         | put new OpenStreetMap maps on an old Garmin 62s like it's 2010.
         | I recently replaced my Apple Watch by a Garmin Fenix 7 Pro and
         | even though it's not really advertised, it just accepts good
         | old map .img files. I put on the Dutch cycle network overlay
         | without any issues, just like I did with my Garmin GPSr units.

       | hook Doom up to the internal nav, then you can ride your bike

       | It's an example of modern tech capitalism: you buy a nifty

         | 
         | They have longer battery life, more predictable performance,

         | 
         | I'll always prefer my specialized equipment for serious music

         | I have an iPhone that I believe was damaged in this way.

         | So you'd probably want a purpose built bike computer, an older

         | are fancy vibration dampening mounts that could work.
