There is also a problem with the OBD MX/LX scanning tools for all who want to use their iDevice such as iPhone/iPod touch or iPad. They just don't work with them. Only the automatic and the OBD MX Wifi work with mobile apple devices. http://www.obdlink.com/mxbt/
So if the automatic really doesn't work well the OBD MX wifi is clearly the best choise because it works with all devices with wifi. (Pc, iPhones, Androids, …) http://www.obdlink.com/mxwf/
