Just a note to say that it is possible to avoid dealer unreasonable pricing and update the firmware and maps.

A few 3rd parties do it for a fee, but you can do it yourself. I have managed (with a bit of mucking about and learning) to get the HN+R EU AU K0900 updated to HN+R EU AU K0942 4, as well as replace the 2012 maps with 2021 versions.
