I just bought a 1999 Rialta and it has no manuals. The Radio/TV in the dash is a pioneer - i have tried to play regular music CD - but it says can not read format. Can anyone send me a link that explains how this works.
You'll need to find out what model it is. If it doesn't say on the front, you'll need to pull it to find the tag. Winnebago used Sony or Panasonic units, so yours was replaced by a previous owner.
