I have done all this. I took my radio out 5 times to recheck all connections. It works, but when I start driving, I get the p brake lead message or w/e it is and then half my settings are gone and song labels don't show and stuff and until I come to a stop, everything is enabled. This leads me to believe that my unit requires both grounding and hacking the software. I have NO idea how to do this, so can someone PLEASE tell me how to hack my radio step by step, and not just say "data.zip"
