Changing map Uconnect 8.4 Journey 12/12


Recommended Posts

The unit will not like your map as the primary because the basemap and unit are tied to the US region, so it will reject a main map for Brazil.

You can TRY to install a supplementary map (an unlocked map of your region in the appropriate format, but named gmapsupp.img). I'd try a small map first . . . . put the map onto a good USB key (the unit is VERY particular, try a class 10 microSD card in an USB adapter). Format the key, put the map into a folder named garmin and nothing else on the key.

Insert the key, put the vehicle into the accessory position and see what happens. You may have to select the map in the settings if it installs properly.

Note that you must keep the radio working throughout the entire update process or you might end up with a brick - and the accessory times out after 30 minutes, so you will need to press the start button 3 times every 20 minutes or so, making certain you do not have the doors open when you do.

If you aren't 100% certain of the procedure do not begin it.
