Won't connect at all. response to developer; I did try all that you suggested, and more. The red power light comes on, but only when I first install it, then eventually goes to sleep without ever connecting to anything, including the app. I have two other scanners that work just fine, as well as a second phone with the same results. As my return window closed a few days ago, you have a chance to remedy this. I will be more than happy to give 5 stars..... When it works.

Possible reasons for not being able to connect 1. The APP does not have Bluetooth and location permissions 2. The car scanner does not support the vehicle's communication protocol For problem 1, you can reinstall the APP and try to authorize it. For problem 2, you can confirm it on another car

it's ok. it has a nice interface. and is very simple and straightforward to use. however it did not have my make of car, Oldsmobile. but other than that it's just very basic in its abilities it just detects the common sensors like water temp engine load throttle position are temperature your mileage instant idling and overall consumption. it has a little bit of the o2 sensor readings and your ignition timing. but compared to something like torque or torque pro which I usually use it falls behind
