I have a Rover 45 car 2002 model with a Blaupunkt R.D.S. DMS. car radio. We changed a part on the car and ever since that has happened we are not able to switched on the radio. We thoughtthat 1H meant 1 hour so we waited 1 hour and then it reset itself backto reading 1 hour. We even disabled the battery for 5-10 minutes but yet we still got the same message. How do we resolve this issue?
