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

This works as expected! And super easy to use. Worked on both our tundra and 4Runner. Don’t be a dirtbag and return it after you used it for what you needed. The money spent to do the few changes I was able to do is well worth it. Order the unit, get a month subscription, I did a year bc it’s on special, and then just hold on to it. Don’t return it with a lame excuse. This product should be non returnable if you cut the tape. It works as expected.

I just picked this up this morning and have already made some nice changes.My car is a 2024 Corolla Hybrid SE, made in Japan, bought in the US.The main things I wanted to change was (1) to remove the seatbelt warning and (2) enable all windows to be rolled down by using the key fob when the car was off. (1) was easy and worked perfectly. (2) worked as well, but there's a hitch. I also wanted to be able to roll them back up using the key fob but that's not an option as of now. I've seen YouTube videos of other Corolla that do have that feature unlocked so I'm not entirely sure why my car doesn't.In my search for that answer I discovered that the Carista App has a beta version that has a lot of other experimental features. Since those features are a work in progress you've got to understand that is may not work completely up to par. When I signed up to be a beta tester I was hoping that the window roll-up ability would be hidden in there but it wasn't. I don't have access to that at all. "Yet" I hope.I didn't really mess with any of the other features outside of customizing so I can't speak to the other 4 menus I skipped. I'm sure there's some good stuff in there.One last thing I'll mention: As of now the Carista OB2 things for sale on this page comes with a month long trial. In order to get that you've got to select the yearly subscription when you sign up. It won't charge that yearly price until you month is over and you can cancel it before is does.I'm summary, it's pretty neat! I really look forward to what other features these folks are going to bring to us. It's kinda cool!

doesnt provide many options, only needed for turning off the seatbelt chime. But then another use for it arose, and i had to pay an additional 30$ to use the thing, because it requires a monthly subscription. I would buy a nicer scanner that is not connecting to your phone and requiring subscriptions. I could see if it had full functionality, but it does basically nothing. Check engine lights it shuts off, turn back on instantly. Features like "turn key to the right and hold for 4 seconds and it rolls down all your windows". Well this feature causes your door to no longer unlock via the keyfob and now requires opening with the valet key. My fault for thinking this company wasnt money grubbing with a product that doesnt even deliver.1 star because it sucks.

Has limited functions but that is due to vehicle. A bit slow but works as advertised. Fee for using it is somewhat high.

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.

Worked on 2025 Camry SE to remove seatbelt chime. It still chimes when starting the car, and the light still flashes, but the chime does not continue to ding repeatedly while driving. Also worked to extend lane change signal duration. I paid $45 for this then $15 for one month of their subscription, but will cancel it once I get everything the way I want it. I guess I’ll have to pay another $15 if I want to make more changes after a month.

This allowed customization of my Tundra TRD PRO. Would highly recommend. Simple to use.

Does change programming for truck. Also probably useful in future for code reading and resetting maintenance recommendations. However, company advertised 1 month free with sign up. I paid thru Apple and cancelled after 3 days.Company still placed charge a week later. Will try to see if module still works as I was supposed to get a month free. After filing complaint with Apple, charge was refunded, but system was also inactivated. Waiting for response from comppany to honor free month.
