Worked immediately and worked well

My 2015 Prius V had this annoying beeping that started when the car was put into reverse. It was loud and obnoxious. The funny thing is that the sound is only in the cabin of the car, it's not heard outside the car where it might warn by-standers. Although almost all of the car settings can be changed using the set-up application on the car's multi-function display. However, the reversing beeping was not one of them; this setting had to be changed by a Toyota dealership. I checked with several dealers in the area and they all wanted > $150 to turn off the beep. Astounding! People online pointed me towards the Carista OBD2 unit. They'd all had success with it, so I purchased it. I'm glad that I did. I plugged the Carista in, it connected right up to my iPhone. Inside of about five minutes I had changed the beep from a constant beeping to a single beep (when reverse is engaged). My sanity was saved! The price is right, the function perfect. I like products that work as advertised! The only down-side (of which I was aware when I purchased the Carista) is that you have to make an in-app purchase in order to change the setting I needed to change.
