Hello.  I am just one click away from buying this head unit  jY-UOS02N4GS-H

One question that i have not still found answer is keeping me from ordering..

This IS elm327 1.5 dongle and your site says this head unit works with Elm327 dongle.
So.. if you can confirm that my KONNWEI ELM327 dongle works with your head unit ican proceed with my order!

Thank you!
