MrBlueSky Posted September 18, 2016 Report Share Posted September 18, 2016 Have a look through that Guizmo guys threads, hes posted up loads including backups of "My Flash drive"....you might be lucky and find one researched to be relevant to your unit ( I haven't a clue ). Not sure it matches your unit, but better than nothing - why the hell would you not backup the entirety of your own nav before doing anythng, beats me ! But stupid is as stupid does Also, I know people have had some success with Diaftias mods with bricked units ? So couldn't hurt if its already bricked, to clear the flash folders with what you download here. Won't have any maps, but you can add your own later. I found the 2015 q2 with updated licenses in the apl2 work just fine but I have a 710bt. http://avic411.com/index.php?/topic/30224-diaftias-hybrid-mods-v36-updated-041911-now-with-auto-installer/ Quote Link to post Share on other sites
