hi all. just fitted a canbus headunit and 7" screen in the 250.it was all plug and play untill you get to the rs monitor. the kit just removes it. so i bought a patch lead and spliced the can low and can high into for the feed to the head unit. thats the way it got feed in the kit originally but you lost the monitor. anyway all works fine..except the obd2 dongle i want to use for the torque app wont connect. if i remove the monitor i.e. unplug it the obd2 port connects and torque app works but no monitor. anyone clued up on the stuff can help.
