Hello ,
i would like to install this
https://www.joyingauto.eu/joying-new...ar-stereo.html
i will add the backup camera

but does it make any sense to add the OBD2 module ?
is there interresting information to display on the screen ?

another question , i saw that there is a third connector at the back of the oem stereo, it's only for amplifier ?

regards
