hi guys, i want to known information about some ELM327 bluetooth OBD2 device which can interface and really work on honda city 2004/05 models.as far as i know, honda city 2003-2008 models use ISO 9141 protocol for communication to ECU. i recently bought the cheap blue ELM327 bluetooth scan adapter which does not work on my honda city 2004. response needed from people who have actually used ELM327 adapter on city 2005-05 and are 100% sure. i do not want to waster my money on something which will not work. thanks in advance.
