I am pretty tech savy so I tried to update my 2011 Genny sedan with the 2018 cd navigation update from MnSoft on my own. Although MnSoft states this is a dealership job, It really seems pretty straight forward. My dealership sold me the cds for about $150. After some 4 hours and following the directions on Youtube explicitly, the infotainment system firmware update went well but the nav screen keeps cycling. Everything works but the navigation. I get the "navigation system is starting up" for about 25 seconds and then a map or the menu for about 2 seconds, and this keeps repeating. I understand from talking with both MnSoft and the dealership that the cd updates are risky. But I wonder if a simple reboot of the system would clear this loop? I already disconnected the negative battery terminal for several minutes to see if that would do it with no luck. I have been into the engineering menu and seen the reset options but don't know what all the codes are for. I really don't want to invest more to have the dealership spend 5 hours to fix this if there is a better way. I am wondering if I should attempt the software reinstall again or bring it into the dealership? What would you do?
