well, when i installed the radio & tried to bypass it, it worked fine for a day & then it started to reset itself over & over while I was driving. When I am at a set place, it works fine. I hooked everything back up the way is supposed to do with no wire bypass & it still didn't work. So what I did was, disconnect the Navi antenna & it works great except no navigation. How could I fix this & is there a way the software could be bypass???
