I noticed in the last few days that the emergency brake warning screen would just pop up during driving. I finally narrowed down that, when I proceeded to drive over 80 mph the brake warning will appear and disable the navi. I made my changes to the ini file prior to all this and set the speed to 128. it works fine up to 80 mph. Has any one experienced this? It is constant, so anytime i go over 80 for the first time. Thanks
