Hi Mikey,
If you have bluetooth as well, then yes it needs programming into the new display.
Does the CD70 light up at all?
Had quite a few where the CD70 has been dropped of fascia removed and put on wrong which breaks off the connector on the circuit board for the fascia and nothing works. If the buttons don't work and it doesn't light up then that may be the problem.
If you do any activation and deactivation of theft protection with the bluetooth fitted in the wrong sequence it can mess up the UHP4 as well.
