Works to customize 2015 Prius – Carista OBD2 Review

First of all-- I'm not a fan of their pricing model. To get any functionality from the app, you have to pay. And the $10 per week, $40 per year doesn't provide value to the customer. Carista should consider softening the pricing model and consider customer value when selecting pricing (hence a deduction of a star). That said, the app worked exactly as intended to customize settings on my 2015 Prius that otherwise would have required a costly trip to the dealer (and possible have the dealer deny changing said settings). A few things I was able to change on my Prius that I LOVE: 1) Turn off the darn reverse beep. There are two settings: 1) beep incessantly that makes you want to shatter your GPS nav touch screen, and 2) beep once. The Carista app successfully changed this to beep once. 2) Turn off the setting that turns the blowers on max when you turn on the front defroster. Factory setting: max. Noisy and annoying. Customized setting: fans go to a mid way setting, which is just as effective and much quieter. There are a slew of other customizations available for the Prius that the app developers website details per car make/model. Even though the pricing isn't ideal, for $10 for a week license you can make any necessary changes using an OBD2 adapter and never have to look at it again. I just highly recommend you have a plan for which settings you want to change and then try out those settings to see if you like them better than the factory/stock settings.
