Connect With Your Car Like Never Before


OBDLink MX Wi-Fi is recommended for Apple iOS.

OBDLink MX Wi-Fi is like a swiss army knife for your car. With the OBDLink app, you can use it as a diagnostic scan tool, trip computer, logger, and real-time performance monitor. This pocket-size adapter won't obstruct driver legroom and features unparalleled performance, intelligent sleep mode, strong Wi-Fi security, exceptional third party app support, free lifetime firmware and software updates, and a modest price tag.


Maximum Vehicle Coverage

OBDLink MX works with all 1996 and newer cars & light trucks sold in the United States (except hybrid or electric vehicles). It also supports EOBD, JOBD, and all other international variants of OBD-II. The OBDLink proprietary connection algorithm enables MX Wi-Fi to connect to more makes & models than any other scan tool.


Acts like a hotspot, or connect to an existing Wi-Fi network

OBDLink MX is the only OBD adapter that gives you the flexibility to easily connect directly to your iPhone or iPad, or to an existing Wi-Fi network. Connect to your home Wi-Fi network, a Wi-Fi enabled vehicle, or practically any device with a built-in Wi-Fi hotspot. MX even supports WPS mode, making it easy to securely connect MX with a WPS-enabled router; all you have to do is press two buttons and you’re connected!


Strongest Wi-Fi Security Protection

WPA2 with AES encryption is a sensible precaution to keep hackers from accessing your car's network. Unlike generic Wi-Fi adapters, MX Wi-Fi uses strong encryption, does not use an easy-to-guess password, or display the password publicly to protect the communication link. A potential hacker would require knowledge of the unique WiFi Key, in order to connect to it.


Includes Free Exclusive iOS App and PC Diagnostics Software

OBDLink MX includes the free OBDLink app for iOS, which work exclusively with OBDLink products. The OBDLink app is packed with outstanding features that make it easy to access, graph, log and export real-time engine data. You can also clear the 'Check Engine Light,' read all diagnostic trouble codes and research them online, check emissions test readiness, and calculate instantaneous and average MPG. Want more gauges? Create a custom live dashboard directly on your phone or tablet! MX is 100% compatible with the ELM327 command set, which lets you use popular 3rd party apps like Dash and DashCommand. OBDLink MX also includes the free OBDwiz diagnostics software for Windows PCs, laptops, and netbooks.
