In order to use the Razr Maxx as a mass storage device with a car stereo, you must go into Menu->Storage->Disable Software Install. This is easy, except you have to do it every darn time you want to use it with the stereo. Not the biggest of deals, but it would be much less of a PITA if you could just set it and leave it. Does anyone know of a way to permanently disable software install? After root, perhaps? Thanks!
