You need both units if you have the DSP system.Niallc said:Jakg said:I connected them to the two wires on the 3-pin CD changer plug - one is +12v, one is ground and one is IBUS (the white one).Niallc said:Thanks for your help Love this forum. Do you know how the 2 bare cables connect?
Why it's not wired up like that in the first place I don't know.
The +12v is a permanent live, the seller says the bluetooth unit turns off after 15 mins. Not sure if the DSP one does the same.
Do I need the other Bluetooth interface as well?
