Shouldn't reboots be an exclusive feature of Windows-based OSes?
It doesn't seem so.
This morning, while driving, I turned on my Yaris infotainment system with the MODE button on the steering wheel.
It turned on as usual with the FM station tuned in. (Bad design here: it was on the USB player when I turned it off yesterday)
I pressed MODE again to switch to USB and bang!
The screen showed the Hybrid logo of the boot sequence.
After that, it correctly switched to USB.
QNX should be a crash resistant OS, able to reload only the offending module.
Reboot was really fast, barely the time to think "what's that?" and the system was back on line: however it's not an excuse...
