Roadmate 800 CD's?

I understand that the Roadmate 800 came with two CD's of software: one for MP3's and so forth and one for loading custom POI's into the device.

Does anyone know how I can get a copy of the CD's, especially for loading of custom POI's? I recently inherited this device when a relative passed away and have not been able to locate any disks that came with the unit. Thanks.
