I bought my Jazz SE in May. The error messages and reboots did not start until I'd had the car for 13 days. My Honda dealer tried a software upgrade. Like with a factory reset, the problems went away for a while but then resumed. The error message comes up at least once almost every day, with a reboot on a majority of days. I make minimal use of the system so far - just using the radio. The radio goes off if it reboots, and it forgets what channel it was using. My dealer has a long list of people he will need to phone if/when Honda come up with a fix for this, and he tells me that other new Honda models are affected - not just Jazz. It's coming up towards a year since my Jazz SE model was launched, so it really is time Honda got it working.
