Why does the Honda RoadSync application not support Israel?

It’s not supported in the US either. but to circumvent, create a second account based in a supported country, sign in and download it.

Then sign out and back in with your regular account. Follow the ordinary instructions for pairing going forward.

I don’t think there is enough demand from countries for Honda to develop it everywhere, or can’t think of another reason

Stay away from side loading or weird dev stuff and in the safety of the garden of Apple.
