1992 300E Becker radio failed. Antenna goes up. No signals received. Rebooted by disconnecting battery. Entered radio code. Radio works for a few seconds and shuts off. Error code E2 shows on the radio. Checked fuses and the 7.5 amp fuse on the turner in the trunk OK and have 12 volts going to the turner in trunk.
Car has been sitting for about 4 months. Any thing else I need to check or do?
