This works for all functions on the original remote. The codes from the built in database are used whenever possible and macros are used elsewhere to get around the toggle bit situation.
Here's an M5 file with the XM Roady's "power" IR command and the 10 presets. Unfortunately, the Roady remote uses a parity bit, so that's all the commands that can be effectively used with the MX-500. Maybe others in the same boat will find the file useful.

This is designed to get around the Delphi XM remote control "toggle" bits, by creating two XM devices, and then alternating between the two each time a button is pressed. Included are the two MXD files and a readme.txt file. These files are desgined for the ROADY/ROADY2 remote, but will work with the SkyFi remote as well. Instructions on modifying the devices are included in the readme, so that changes can be made to accomodate other similar remotes.
