Does anyone know how to set these things up? I bought this bluetooth obd adapter: Super Mini OBD2 ELM327 V1.5 Bluetooth Car Scanner Android Torque Auto Scan Tool | eBay and cant get it to work with anything. I've tried Dashcommand using roqyBT4 and REV on my iphone, and Scanxl pro (on my mates pc) and Scantool.net on my laptop. I've also tried it on a 2004 ford fiesta and a 2006 lexus rx350. Am i missing something ?
