I have lately installed an android headunit purchased from a local reseller on my Mazda CX-3 2018
the unit needs a canbus decoder to interface with the original car settings. and everything working fine besides the OBD2 port
when the canbus decoder is disconnected - obd2 works (connection to ecu is succesfull)
once the decoder is connected - all car canbus stuff work , but obd2 stopps working! - getting power but cannot connect to ecu
after going back to the seller he found out that the harness that is connecting to the canbus decoder is sending both canbus info and obd2 on the same wire (wtf!??!!?)
we found a single wire thats when connected - allows canbus connection to the headunit but kills obd2
once disconnected - no canbus to headunit but the obd2 returns to life..
Did anyone encounter such an issue before?
this is the closest product to what I have that I was able to find online -
p.s if more info is needed ill be happy to provide it
thank you
