hochiinn Posted August 10, 2019 Report Share Posted August 10, 2019 a few weeks ago, i updated to 2018 Q4 maps(southwestern usa) by sd card. the other day, i was looking at avic-sync on the iphone, went to sales, and in there are also 2018 Q4 southwestern usa, plus north america. do i need to download them to the iphone for Q4 maps to work? is there anywhere i can look to see if everything has been updated?
