After much searching (and not finding) on Prius forums and KZfaq channels for an up-to-date how-to video that recommended a free app and cheap ODB2 device, I decided to make my own video.
OBD2 Bluetooth interface $9.89 & Free Returns:
Mestart OBDII OBD2 Bluetooth Car Diagnostic Scan Tool Auto OBD Scanner for Android Devices www.amazon.com...
Dr. Prius on Android:
play.google.co...
Dr. Prius on IPhone:

PS Carista OBD2 app is free for diagnostics only. Customizations such as disabling reverse beep cost another $10-15
Thanks for watching! I apologize for the bad hair day 😂
And thanks to all those who have done videos and provided info on forums before me.
