Hi, just got my player and am trying to get it hooked up. When I plugged it into the AC power the screen comes up and says RIO on it. And that is all it does. When I try to power it up in the car it wont even do that. I am putting this in a 1991 Rodeo. Is is possible that I have a defective unit. Also when I installed emplode I cant get it to see the player. Thanks for your help.
