MK1 fabia- what's my options

Currently have the symphony single cd fitted and I'm quite happy with it. But thinking into the new year, I'm wondering what are my options to fit something else.

I've got the recommended AUX socket but for some reason i couldn't refitt the HU with it in place so removed it again. I've got a VW 6 Cd changer (dash mounted) as well with works well but needs some messing to get the illumination working when you put the lights on (not sure if it has any, any one know if it glows amber in the dark when you put your lights on) . So is there a double din HU that'll fit the MK1 stereo console? Preferably a Skoda one but I'll go after market if I'm pushed. 

Any info appreciated
