Question: The Topdon Artidiag Pro can do a lot for the price. I would like to have Czech language. Does anyone have experience with this?

Answer:

The ArtiDiag Pro does not currently support the Czech language.

The ArtiDiag Pro is one of Topdon’s older models, so it is no longer receiving language updates.
However, many of newer ArtiDiag series devices do support the Czech language, i.e AD900 Lite, AD800BT 2 etc.
