I don’t think a heated windscreen is fitted in European market Jazz models.
I saw a Japanese Fit video showing a heated windscreen button in the switch panel that includes the parking sensor and headlight aim adjustment switches but think this may only heat the windscreen wiper part of the screen, same as fitted to some Kia models.
The Japanese market windscreen also appears to include a green tinted sun screen across the top edge of the glass.
The UK website specs still show a rear centre armrest, which is included in the Japanese spec but don’t think this is fitted to any European Jazz models. The Republic of Ireland Honda website also shows tilting mirrors in reverse as standard from mid spec and above (SR and above UK equivalent model) but again, I don’t think this feature is actually included.
