Batboard

I have 2 GM300 radios and a RICK that I am trying to make in to a crossband repeater. I have searched the forums and can't find any information regarding to the mode of the GM300. I assume the radios need to bein the Repeater Mode with the RICK mode selected in the RSS. When I go to program the radio I get the following message. "The Accessory package selected is NOT supported by the current ROM Version. Contact Prodcut Services! -- F10 -- ABORT". Has anyone seen this message before? What do I have to do to get the ROM to support the accessory package? Should I put the radios in radio mode, make the patch cable and skip the RICK?

Cheers!
