After purchasing a [ PX6 Six-core ] 12.1" Vertical Screen Android 9 Fast boot Navi Radio for my 2004 Lexus LX 470, the technician Chris was very supportive and knowledge for me to completed the installation and operation of the new unit. He responded to all my questions and provided additional files requested for me to customize to me needs.

Definitively, I would recommend Phoenix Automotive product for their products and technical support.
