Electric Wing Mirror Not Working

[ASW]

Hi
I have recently updated the audio system in my 2015 T6.
As part of this I had a windscreen Dab aerial fitted to hopefully improve reception.
I have recently tried to adjust the passenger wing mirror using the control button with no luck. The drivers side mirror works perfectly.
Could this be anything to do with the original antennae being disconnected and if so what can be done.
Thanks
Andrew

The original aerial is normally in the passenger side wing mirror, so quite likely this is the cause of the non-functioning wing mirror now.
