As I understand it, after 2018, the Prius information head was changed to a new brand and there is no new updated map available for my Prius anymore. Was the information head in my Prime unique from ground up design including the map system so that whoever manufactured my system no longer can supply a new map card? In other words, would this manufacturer have made similar system for other non-Prius manufacturers, but their mapping card could fit my car so I could get a 2023-2024 card and get my Prius mapping current? Thanks
