ScanTool OBDLink MX Wi-Fi: OBD-II Automotive Adapter / Diagnostic Scanner for Windows, Android and IOS – DIY Car and Truck Data and Diagnostics

Compact OBD2 device which fit snug out-of-sight in the OBD2 socket under dash. Connecting this directly (peer-to-peer) with your device's WiFi you will lose the option to get an Internet connection, however you do get the option to connect the OBDLink MX first to a mobile hotspot or a wireless router (via the OBDLink MX's local web settings). Setup was pretty straight forwards: 1. Download OBDLink App via ScanTool's website or AppStore, select and setup your car profile settings; 2. Plug OBDLink into ODB2 socket and switch ignition key to ACC; 3. Hold setup button on OBDLink; 4. Turn on WiFi on phone/device, find and connect to "OBDLink MX", and input pass code; 5. Start OBDLink App and connect. Downloaded 3rd party app called "DashCommand" from AppStore for a small fee, slightly buggy with intermittent connection issues to ODBLink MX (connection dropping out frequently and popup messages asking to enable bluetooth). The default OBDLink app is pretty reliable, the only connection issue (happened once) was my phone's WiFi connection dropped off "OBDLink MX" and connected another WiFi connection/hotspot, which meant the connection on OBDLink MX must have dropped or the device auto rebooted for some unknown reason.

Purchased the WIFI version to compensate for a lack of gauges in my turbocharged MINI Cooper. Couldn't be happier with the purchase. Setup and configuration was quick and painless. The corresponding app (iOS for me) connects to the device quickly and, once connected, data is displayed in the app in real-time (zero noticeable delay or 'latency'). While I primarily use the OBDLink MX to display engine data, the app allows you to access a large amount of status related data and engine codes with the click of a button. Note: There are a number of Bluetooth and WIFI devices on the market. However, my tuner recommended this specific unit as being most compatible with the iPhone and iOS. I'm glad he did as I've had zero problems. Pros: Ease of Setup, Device Quality, App Features, Real-time Data from Device to App, Price (great value) Cons: None

I was so looking forward to this after reading all the good reviews. Once it arrived, went straight out and tried to tap into my truck. No matter what I tried, the damn thing would not connect to my phone. I have an ipad, so thought I'd try that to see if it was maybe defective or an Android issue. Connected like clockwork on the ipad. Used the app, and worked great via ios. Hmm .. I'll try my andriod tablet to see if it's possible a Nexxus thing. Connected fine via tablet and software worked fine. WTF? So tried again with phone and after several fails, it connected. Well, maybe a firmware upgrade happened behind the scenes? I'm not sure, but was satisfied for the time being. Few days later took to another car to reset the code and it all worked great. Past tense though, as now when I try to connect back to my truck, takes forever to connect, then once it does, the software says I have to register to continue to use it. I can't upgrade the app unless it's connected it seems which it won't do as it immediately disconnects after telling me to register. It's just a large circle jerk. Whoever designed the workflow of this item along with it's companion app, is a moron. My last scantool purchase.

Very handy tool. It was easy to setup and use and paid for itself on first use. I was able to diagnose the check engine light on my VW Jetta which led me to a part that I could fix on my own. Saved me at least $400 in repair bills. I especially like the ability to leave the device plugged in and connected to the iPhone. You can see all sorts of vehicle information like, MPH, RPM, Turbo Boost Pressure, Miles per Gallon, and many more. You can make a custom dash displaying readings from essentially every vehicle monitor in real time. I have on occasion had to remove and reconnect the device to the cars computer port to get it to connect with my phone app, but I would still give it 5 stars as I don't know if that's a bug or user error. It's a great tool to have even if your not mechanically inclined. You can google the trouble codes and at least know what's wrong with your car before you get to the mechanic shop.

Too expensive for what it is, but that's because there's a lack of secure OBD2 WiFi devices on the market. The OBDLink app is one of the best but lacks documentation. It kept causing my Vauxhall Onsignia to stall, but I eventually found out from searching the web that the app can overload the ECU in the car causing it to crash & stall the engine. So I reduced the polling rate in the app Which seems to have fixed it. As with so many products, a great idea let down by lack of comprehensive help documentation. Has come in useful for DIY diagnostics and General DTCs but cannot show all proprietary Vauxhall DTCs that garage can with specialist equipment. I blame Vauxhall for lack of openness & trying to force people to have overpriced work done at dealers.

... très cher pour ce qu'il offre. De plus il empêche "les donnés mobile" de fonctionner donc pas de guidage gps possible en même temps. Je précise le but pour moi était d'avoir les défauts, évidement, mais surtout les manomètres (t° eau, pression turbo, ...). D'autres lecteur OBD font aussi bien, sans doute avec une interface moins sympa, mais pour un prix 5 fois moindre.

I have bought this device and connected to my iPhone with iOS 10.1. The connection is successful and I'm able to start the relative app. I have the problem that every few minutes the wi-fi disconnects, so the app stops working. I need to go to the settings, reconnect the wifi, then go to the app and reconnect. This every 5 or max 10 km, not very usable. I've also tried to not put the phone in stand-by, but without any better result. In the current state the unit is unusable. I'll be glad to update this review if the company is able to fix me these issues.
