Try this and see if that helps.
Connect all the necessary wires. Put all the wires behind the HU.
If you have removed the passenger side footwell panel (under the glove box), and routed the wires from there, then use that area to bring all cable back as far as you can.
And with it, start pushing the HU back to its position.
