RADIO RESET

I BUY A RADIO FOR PEUGEOT PARTNER 2005 MODEL CAR. THE OLD RADIO WAS CONTINUOUSLY RESETING ITSELF, THE RADIO I Bought NEW IS CONTINUOUSLY RESETING ITSELF. AFTER 2 MINUTES AFTER TURNING OFF THE VEHICLE, IT GOES INTO ECO MODE, ALL ELECTRICAL COMPONENTS TURN OFF, WHEN I TURN ON IT AGAIN, IT IS RESET. CAN YOU HELP SOMEONE WITH THIS SITUATION AND SOLVE IT?

Your problem may be caused by the battery, or if there is a play in the installation, it may be a wrong connection.
