I'm getting the same problem. I turn off my ignition and the player goes into "the rest mode", but if I press play it comes alive again---with the ignition off. I checked the conection at the ignition wire and it reads 0 volts, but the player still plays? This may also be related to a problem I'm having with the unit shuting off when I hit the brakes. Sounds like a factory defect to me. The only reasion I say this is because I know I'm not the only one here who has this problem. Plus this also sounds like a hardware problem.
