figures Posted August 17, 2018 Report Share Posted August 17, 2018 I have AVIC U220 and the SD card only has one file called device.dat in the AVIC-APP folder. I am trying to update the Navigation I will be honest with you, I have no clue how to go about doing this. Any help will be appreciated it. I was able to get my hands on Pioneer 2012 map upgrade but dont really know how to go about properly transferring that onto the SD card. Quote Link to post Share on other sites
