That's one thing that makes me leary of the OBDeleven apps. Do the apps tell you everything they are going to change or do you have to review backups to figure it out? Some of the coding changed between different years and I don't know if OBDeleven has a way to account for that.
I stopped using my OBDeleven after it somehow added a Radio Module 56 that I could never get rid of. Infotainment on our cars is the 5F module which I still had. I checked my Gateway installation list, even re-registered modules and it always showed up. Didn't go away until I had the my gateway replaced with a highline (not for that issue, but it was a nice suprise). OBDeleven remains in the 3d printed glovebox holder I bought from Southpawboston here on the forums. I would take it out but I lost the piece that used to go there, haha.
