How do I change the language on my Pioneer carrozzeria?
Question : I have a carrozzeria AVIC-****. Can I switch the language to English ?

Answer : Carrozzeria AVIC-**** is car navigation & AV model designed and sold for Japanese market only. The language cannot be changed to English, French or any other languages, and the instruction manual is in Japanese only.

..

Switch between the default ??? (Japanese) and ?? (English).

Some units are made for the Japanese home market and only come in Japanese. One easy way is to use a smartphone with the Google Translate app on it and use the camera feature to translate what you see. Look for Settings - Language.

The Carrozzeria AVIC-HRZ009G is a car navigation system specifically designed for the Japanese market. Unfortunately, there is no direct English version of this model available. Carrozzeria is a brand owned by Pioneer Corporation and primarily produces car audio and navigation systems for the Japanese market.
If the LCD screen of your Carrozzeria AVIC-HRZ009G is broken, it would be best to contact Pioneer customer support or an authorized Pioneer service center in your region. They may be able to assist you in finding a suitable replacement or provide repair services for your specific model.

You have to purchase a frequency converter and get properly install

Possibly purchase a replacement model from the United Kingdom and install it instead of the Japanese model.

Youtube videos might help show menu for similar model, but it still may be impossible to change the language to English. The Pioneer model from Japan doesn't appear to be designed for English. This same question has been asked for many years without a solution.
