Audio Tech Direct have been specialising in Android head units for over a decade. We have our own brand, called PBA. This stands for Powered by Android and is exclusive to us. 

PLEASE NOTE: The majority of head units on the Nissan Serena C26 should be on the Nissan 20pin connection but as there is no catalogue data for this vehicle, it maybe best to show us the stock radio in the vehicle so we can determine what connections it is on. If you have a factory camera, it will most likely be the 6.2v camera and be on a 32pin connector. If you have the roof mount monitor, generally these are on RCA but the RCA connection is underneath the dashboard below the radio.
