Likewise I went to TomTom to get the update and then was guided to the Mopar site for my 7" uconnect satnav. It took a very long time to download the maps, a very long time to extract the maps from the zip files, a very long time to copy them to the 16Gb SD card and then a very long time to update. Just having the radio on isn't enough as the radio switches off at around 10 mins. You can sit in the car and keep Turing the radio on when it shuts down and this does resume the update if you are quick enough. It took me about 8 attempts! And there are very few manuals available for this model. Anyone help with a manuals link please?
