How to factory reset Honda Jazz (Gen 3 / 2015–2020) infotainment system?

Question

Context

I have a Honda Jazz 3rd Gen (2016). For a couple weeks, the infotainment system won't fully start. Indeed, it keeps looping on this sequence:

• Honda logo (15s)
• Honda logo + spinning wheel (ca. 60s?)
• blank screen (2s)

It all looks like a software issue to me. I have tried to disconnect the battery for a few seconds, but this had no effect. I've also tried to push radio's on/off button for 20s+, without success.

How to factory-reset the infotainment system?

Answer 1

My issue was similar to the one described in this forum thread… and the solution as well!

I had to simultaneously press for a while (ca. 30s) on both the power and the brightness-level buttons, as indicated below.

The system then reboot, and asked me to press the power button for 2 seconds (anti-theft program)… and it was then all good!
