heres what i did........................
took a straw and blew into the head unit to loosen some of the dust that may have got inside. i also cleaned the bottom of the cd....it has a few scratches on it so i think that may be the problem....when this happens if you look into the connections menu it says the satellite cannot be found.......i dunno what to do ...its been working a little better as of late, but this is b.s. man
