I used to have ELM 317 bluetooth i got 3 years ago from amazon for $14 however that thing does not work with 1999 Accent for some reason when i use with Torque on android it connects to adapter but cannot communicate to car ECM staying on "checking model..." status forever.

I guess its because that adapter did not support protocol used by hyundai properly, do you know of any cheap bluetooth dongle that works for sure with X3 model?
