I am having an issue with my 07 21V gauges and I'm afraid that the Medallion module has gone bad. I have found one for an 09 online for a good price ($100), but I'm not 100% sure if it is compatible. Does anyone know if there is any difference between the 2 displays. I know the dash looks the same, but I don't know if Perfect Pass works the same, or any of the other stuff that cute little magic box does.
Thanks for the help
