Pioneer head unit installation

[gazza222]

Hi, after much messing about trying to get my RNS510 to work, I've decided to put the pioneer avh-x5700dab unit out of my T5 in instead. Now the hole the 510 came out of seems bigger than the pioneer going in ! I've got the new fascia and surround for the front of the dash, but what supports it at the back ?. Do I need a different black plastic cage or is there another part I need to get ?
Any help or part numbers would be brill.
Many thanks
