ROM 103 Compatibility?

[Wyzzard]

I have a VIRGIN ROM 103 card that I am trying to use in either a 501 or 510 receiver. When I put the card in the receiver it goes thru the 1-5 setup menu then gives me a screen telling me that this card is not compatible for this receiver. It did this on both models. What receiver is the ROM 103 compatible with?

If im not mistaken Rom 103's are only for dual tuner receivers
