That is probably correct. Lexus is not making the maps and if not selling a lot of them, buying the maps cost more than they make selling them even though they are horribly expensive, Lexus is not making money that way. I bought the update map in November and instead og getting a 2020-21 (which has been sold on eBay since October at least) I got a 2020.
Lexus here on the island does not need to have service of quality as no competition is closer the 1.2K km on a boat lasting 2 days and boat fare costing more than the Lexus map.
Instead of buying maps it is cheaper using a smartphone. Not funny having a loose phone floating around. Still have an old Garmin to put on windshield with a suction cup with free updates of maps, but having the loose power wire is not fine; Is there anything that can put the maps from the phone on the built in screen, via Blutooth or USB connector?
