Had to replace the car battery. After this the stereo will not function. I only get a STANDBY signal. I tried reset button many times with no results !

mickkko, you may have a bad switch. check all you r switches with an ohmmeter and make sure they all measure above mega ohms. as for guest, if you can, disconnect power to the radio overnight and see if it resets itself then. sometimes the resest switch doesn't always clear the microprocessor.
