Shackleton Posted October 10, 2014 Report Share Posted October 10, 2014 Any reason to update if you only use the 4000 with an iTouch? Quote Link to post Share on other sites
joemamma1954 Posted October 10, 2014 Report Share Posted October 10, 2014 For myself, i like to have the latest firmware on any of my electronics. I know there were a few things other than CarPlay on the firmware update, but i think they have to do with the AVIC models more than our 4000NEX. Quote Link to post Share on other sites
