There are countless CD-i players from Philips itself and also from other manufacturers.
When identifying Philips CD-i players, always read the version/revision from the type plate (on the back or bottom) to find the correct model.
Example:
CDI220 (or CD-i 220, CDI 220) is not unique and can be one out of five different hardware generations (and even more regional variants).
Correct identification is only possible with the full version; e.g. CDI220/20 for an EU model with Mono I mainboard/chassis.
