I just recently scored a RFM in great shape but I found it still had 1.1 software on it!! It couldn't have been easier to update with a null serial cable. I watched blkdg's youtube video on how he did it. My pc connected with the game at once and now it's running 1.6. Can't wait to get this all ship shape. The diagnostics is awesome and I fixed all of the reported issues already. I'll post pics when I get it all dialed in.
