Some 2018 vehicles built after January 1, 2018 and equipped with Navigation may exhibit one of these concerns after the user inputs an address: A screen pops up that says "House number not found." After the user selects OK, the system finds the address or a nearby address.Instead of finding the correct address number the system adds a digit to the end of the number. Example: You enter 151 and the system comes back with 1510, 1511, 1515, 1516, etc. This only occurs with MAZDA CONNECT software version 59.00.532 or 59.00.540, which started being installed into vehicles in January 2018. The concern can be eliminated by installing MAZDA CONNECT software version 59.00.545 now available on MGSS.
