SOMEONE ELSE'S GOT MY NAME Posted July 27, 2009 Share Posted July 27, 2009 You may want to try this: Remove the DVD from the DVD box With the 400h turned off, disconnect your 12v battery (simply unhook the ground cable ... that's all that is necessary) With the battery disconnected, turn the ignition key all the way on, as though you are trying to start the car up. Turn the key switch back off Re connect the 12v battery With battery re-connected, turn the ignition switch on to accessory mode. Insert the proper DVD and your system may now recognize it. Sometimes your car can hold memory, and by disconnecting the 12v battery and turning on the ignition switch, all stored memory will be drained out of the car's system. Good luck .
