If you look at the specification for the KONA SE it does not have front parking sensors. See here and press "specification" then "Convenience" https://www.hyundai.co.uk/new-cars/kona

A few minutes into driving I get the message "Online data available. Traffic channel will be changed” on the map display, and then it colour codes road traffic conditions. It must be retrieving live traffic conditions but where from and what is "traffic channel"?
