Hi guys, sorry to be a pain and ask such a noob question, but I've had a bit of trouble finding a definite answer anywhere.

I'm about to replace the stock unit in my 05 vectra with a Sony XAV622, and I'm just wondering if I will be able to use the stock cage with the new unit or if I'll need a new one to fit a facia?

I live in Australia and its frustratingly hard to find much in the way of parts/info etc on vectras here, so I was stoked to find these forums! It's looking like I'll have to order the new facia/possible cage from the UK as there are no stockists I can find here at home, so I was just wanting to get an order on the way if need by while I wait for my new stereo unit to arrive! Thanks for any help and patience!

*forgot to mention the new unit is double din, hence the possibility of recycling the cage*
