Radio and power window issues

[Jonesy72]

2006 VZ Berlina. Fitted new stereo and a few months later I'm now having issues where my stereo doesn't hold memory,antenna only works sometimes and so do Windows. Any ideas ? I've been told maybe UCU or BCM. Just hoping it could be something cheaper as I've just had timing chain done

Wired the power and accessory the wrong way.
