Kia have forwarded to me a soft copy of the Niro sat nav manual, which I will attempt to attach to this post.
They have stated 'We’d be happy for you to upload it and share with Niro owners. I’d recommend noting that it applies to model years ’17-’19 because the recently arrived ’20 model features the all new ‘wide’ touchscreen.'
Hope this is helpful
