on the cde-w296 headunit the blue power antennae lead is not on the fly i.e its connected within the twin block output loom from the headunit, and marries to a blue lead in the connects2 supplied wiring when the blocks are connected.
The blue wire then carries on into the canbus reader supplied as part of the connects2 kit.
I'm wondering if this blue wire is meant to go somewhere in the canbus reader......
