My 2016 B Class is in the first set as it has Audio 20 and the SD card I have just bought is 2019 V11 with the same part code. Hi, Having just ventured into this murky area myself here is what I have found out. So when looking at versions that have changed on your advice keep in mind that the dealer may have updated the Audio20 firmware as well. the specific firmware update included an update relevant to the GPS hardware).

Updating the firmware on the Audio20 unit will not affect the navigation software or the maps data, but it could affect the way the GPS hardware behaves (i.e. it seems that dealer updated the navigation software but not the maps.Īlso - the Audi20 unit has a firmware which is yet another bit of software that can be updated. Said that, my post above is still valid, i.e. During the free updates period you should be able to update the maps yourself online without replacing the SD-Card. I suspect that the dealer updated the navigation software, but not the maps data.ĮDIT: Just read your previous post saying that the car is a 2017 model and has 3-years of free maps update. In order to update the maps data, you will need to purchase a new SD-Card. The latest version of the map data will include new roads, more POIs, and previous map error corrections. The second is the maps data, which is not free (from memory it is free for a limited period of time from where the car is new). The latest version of the navigation software will typically add new features, have improved navigation and route planning, and include bug fixes. The first is the navigation software, which is a free update and can be downloaded from the Internet. There are two bits of software that need updating, independent of each other, on the Garmin Map Pilot.
