Fabia II RNS315 Retrofit

Evening guys and girls. New to the forum but not new to the Skoda life.

Mainly had Octavia estates but about a year ago grabbed myself a 2010 Fabia TDI initially so I could do tip runs but it’s such a great little car that I’ve started doing a few bits to it. 
 

I thought it would be nice to upgrade the stereo to something with a screen, for aesthetics more than anything but also to be able to use the Bluetooth functionality. 
 

everything went smoothly, mic installed, DAB aerial installed, gps antenna installed, stereo installed and all worked brilliantly however I was experiencing the dreaded battery drain. 
 

After investigation, I thought I could get away with a canbus emulator, however upon install it would make the climate control backlighting flash and the stereo backlighting flash.

can anyone make any suggestions as to what can be done or an alternative route to take? I have tried to attach a video of the flashing for your viewing pleasure but it’s too big unfortunately.

any help is greatly appreciated
