Hi, some random thoughts, from memory there are no mechanical relays inside the radio, so the only relay he could be talking about would be a relay supplying ACC and IGN +12volts to the radio. However I donít think a separate relay exists for that circuit?
Apart from a 7.5 ampere switched circuit (IGN/ACC), there is also a permanent un-switched + 12v supply to the radio for real-time clock, security and last Radio/CD state etc. As itís appears to be a 10A circuit, I would think that this circuit is likely switched electronically (electronic relay if you like) in the radios and therefore could be the source of the problem.
There would be a number of ways the radio could fail and trigger this fault, without a circuit it would be hard to fix as there is a microprocessor controlling the on/off operation. I have never found a circuit of the internal radio/CD.
