Carista OBD - Bluetooth OBD2 Scanner - Car Scanner Diagnostic Tool and Code Reader with Access to Diagnostics, Customizations, Service Tools, and Live Data - Subscription Required

Worked perfect for my Gen4 Tacoma. Was able to turn off annoying seatbelt chime and adjust timing and sounds on things like turn.signals and interior lights. Needed to download application and use a subscription but was easy to download and use.

Works well. Super helpful when installing subs on cars and you need to remove the engine sound

I purchased this device several years ago in 2024 for my Toyota Tundra to make minor changes to inaccessible settings such as the seat belt chime. I used the device without issue for the one time I needed to. Fast forward to end of 2025 and I attempted to update the settings again but no longer had the option. It only allowed the reading of vehicle outputs and gave hints at making the changes to inaccessible vehicle settings prompting and requiring to upgrade to the more expensive OBD2 scanner in order to do so. Very disappointed and will be researching alternatives. Call me cheap but they took away features only to capitalize on new devices. It’ll probably happen again where the EVO will become obsolete and a new device will take its place.

I used this on my 2023 Tundra, and it worked perfectly for adjusting several convenience settings. I was able to: Enable one-touch up/down for all four windows (no need to hold the switch) Turn off the seat belt chimes — very helpful when towing my RV and jumping in and out while backing up Set the turn signals to flash six times for lane changes Everything programmed easily and works exactly as expected. The only downside is that the companion app requires an annual subscription, which adds a bit of ongoing cost. Other than that, it’s a great product that gives you control over features Toyota locks down by default.

Works as advertised. Slow! I would buy the upgraded version for the faster comms, but it does what it should. New Tundra’s chime doesn't turn off as fast as the older ones. SUPER ANNOYING! This fixed that issue and added a couple other decent features. Also, I would leave it plugged in as I drove. Starting noticing the check engine light coming on and throwing codes that do not make sense. Only plug it in to make changes, and the codes stopped. BUT! $100.00 bucks (app and device) to stop the annoying chimes, worth it.

Does a good job. Although you do need a subscription to do much on it. I got the seatbelt alarm off my truck so I am happy.

The Carista OBD scanner hardware itself is solid. The Bluetooth connection was fair and reasonably easy to set up. It’s a compact and well-built diagnostic tool that does a good job of reading basic codes. However, the main drawback is the software pricing structure. While the initial features you get for free are decent, unlocking the more advanced customizations and diagnostics (which is the real reason most people buy this) requires an expensive subscription. For a casual DIY user who just needs occasional use, the software cost makes this a hard sell. It works as described, but be aware of the ongoing costs if you want the full functionality.

Worked on my 2022 RX Lexus and my husbands 2025 Toyota Camry. Different options each car but each had the ability to disable seat belt chimes and many more options. 7 blinks vs 3 for lane changes, volume of blinkers, what sensitivities for auto headlights and parking assistance volumes, sensitivities. Key fob hold vs single, double press. Lots more. Anyway, cost of unit here plus a month of service, $16.25 after tax and set up our cars. Cancelled service so I don’t get a surprise in a month. If I offer around to friends and family can maybe even knock the entry price down further. Definitely keeping the device. Kind of factored that in after verifying our cars were able to program and cut the void return tape. Good tool! Buy it on sale here or the carista website, depending on who has the sale and purchase a month subscription. No need to buy more than that unless you work at the dealership. Even then mechanics rarely talk to customers. Fleet mechanics don’t usually work on Toyota or Lexus so kind of a limited market but well worth the purchase, imho.

Wszystko super, szkoda że aby mieć dostęp do wszystkich funkcji trzeba subskrybować aplikację, ale i tak fajne rozwiązanie. 1 miesiąc jest okresu próbnego, wiec można sobie włączyć w aucie wszystkie potrzebne funkcje a później w razie potrzeby wykupić dostęp do appki zależnie od potrzeby. Jedną z rzeczy które ja odblokowałem w swoim aucie to np. doświetlanie zakrętów. Ogólnie polecam !

لا يوجد تفعيل لمدة شهر مجاناً لابد من دفع عن الاشتراك

Sehr gutes Diagnose-Tool für unterwegs! Der Carista OBD Bluetooth Adapter funktioniert schnell und zuverlässig mit meinem Smartphone. Die App ist einfach zu bedienen und zeigt alle wichtigen Fahrzeugdaten sowie Fehlercodes an. Ideal für Auto­diagnose und Anpassungen ohne Werkstatt – klare Empfehlung!

This is not for india , I HAVE A POLO , even its a german or imported if the car is registered in india , you cannot unlock lot of features this is only for other countries better go to OBDELEVEN , this carista is not for india

Excelente herramienta para poder configurar varias funciones de tu coche. En mi caso, lo usé para desactivar el molesto "auto start/stop" de forma definitiva (cuando en la agencia se pusieron sus moños diciéndome que eso no era posible), también para registrar el cambio de la batería, y activar algunas funciones que venían ocultas en el menú del coche. Tienes que comprar una suscripción, yo pagué un mes porque no la voy a utilizar mas de momento.
