Welcome to the FCF!

Is the problem with the buttons the only one? Does that radio play music when the buttons are not working?

Do the radio controls behind the steering wheel continue to work?

I think that it is likely that you have a hardware failure inside the head unit, but you cannot really confirm this without changing it, which would require the replacement head unit to be re-coded with the VIN for your car.

A replacement RD4 should not be very expensive, or you could consider upgrading your system to RD45 to get bluetooth and USB facilities.
