Just bought a gently used 2017 Challenger R/T and having issues. Sport mode button does literally nothing, navigation menu won't let me reset home address, and more issues to come I'm sure. Seems like a factory reset of u connect is a place to start, but the methods I have found online don't work. Tried holding temp up and down buttons...Nothing. Tried holding phone and VR buttons on steering wheel...Nothing. Any help would be greatly appreciated. ??
