Thanks everyone, I found a thread with a follow brit who also gave up on removing the trayless model... I guess it is professional help then - frustrating, as it shoudl be so simple but would seem a shame to damage the dash for the sake of a few pounds...
Has anybody fitted a CK3100 to their I30? I would be keen to hear any location tips for the screen, or any recommended brackets (the supplied one seems useless as it relies on an almost flat dash)
Thanks again guys and gals
PS - loving the I30 - we were running a 2001 1.7d Merc A Class, I am truly amazed what a step up the 1.6crdi engine in the 2011 model is in comparison (not being a car type in general) I am a Hyundai convert!
