Thank you for viewing. This is a T-Connect navigation kit removed from a 30 Series Late Model Alphard SC display audio. It's a K0045 2021 Autumn version model. I believe these are still not widely available. This item has a new parts price of 110,000 yen. It can be used with display audio, Alphard, Vellfire, and is likely a simple coupler connection to the vehicle's side. Alphard/Vellfire harness and mounting nuts are included. Other models such as Yaris, Yaris Cross, Corolla series, Prius, C-HR, etc. can be used with the purchase of a separate, model-specific harness. Compatible car manufacturer: Toyota 86840-K0045 Thank you for viewing.
