Hello, I need a purchase advice which OBD2 adapter I should buy. I have 3 to choose from: For 5,15€: Mini ELM327 Bluetooth OBD2 OBD II Car Diagnostic Device Interface Scanner http://www.ebay.de/itm/221681251090?… For 81,98€: ScanTool OBDLink LX Bluetooth – Professional scan tool Android hacker protected http://www.ebay.de/…/201821112741?… For 119,90€ OBDLink MX WiFi Adapter incl ScanMaster OBDLink OBD 2 Diagnostic Software http://www.ebay.de/…/281493471398?. .. With the Mini ELM327 it says that it can not ” ATD, ATFE, ATCEA, ATFCSMx, ATSWxx, ATRx, ATBI, ATLP etc.”. Can the other two or why do you need this? The OBDLink MX has an up-to-date firmware, does the OBDLink LX have that too, do you need it? Are the two expensive ODBLink adapters worth the extra price?
