Modern Harleys, however, have a lot of electronics available, if you want to take advantage of them. I've got a touch-screen unit that includes GPS (including turn-by-turn navigation), SiriusXM satellite radio, Bluetooth (for phone calls or playing the music on my iPhone through the bike's very well-equipped "Infotainment" system), a USB port (for updates and playing MP3s), a security system, a garage door opener, and so on. Other models might have CD players, CB radios, etc. The lower end/cheaper models typically don't have much more than a speedometer. Some of these are, easily, $50,000 bikes, though.
The software updates are dead simple, too. Download a file to a USB stick, plug it in, turn the ignition to accessory, and... wait. It shows the progress/status on the screen and takes maybe 10 minutes from start to finish. Someone like me (more "tech-y") usually gets the USB flash drive set up when an update comes out and then we all just pass it around when we get together for a ride or something. Others don't care and don't bother ever updating.
Even the "grumpy old-timey bikers" like their tunes. :-)
I’m not paying a few hundred euro per year to update them. Even if I did they probably wouldn’t be as good as Google or OSM, as currently the maps only have major roads and cities.
It would be cheaper and more effective to buy a replacement Android head unit.
Contrast that with Harley-Davidson who is notorious for "nickel and diming" and charging outrageous amounts for otherwise regular products. I can just go to their website, download a file to a USB flash drive, plug the flash drive into my motorcycle, and it'll update everything -- including the GPS navigation system and maps.
It just seems backwards to me. I probably wouldn't pay anything for map updates for the car (and I don't for my truck, either), although I might if they were cheap enough. OTOH, I absolutely would pay for updates for the motorcycle but even H-D doesn't charge for 'em.
As long as navigation is available for free on everyone's mobile phones, I'm not sure how automobile companies expect to make much money from map updates.
