Fascia/brace help - buying new stereo

[Damo]

Greetings all!

Well, I just upgraded my 2007 Yaris to a 2011 one a few days ago, and for this car Im looking to get a new stereo.
Ive seen listings of different DIY brackets etc for mounting aftermarket stereos, but Im a little lost.

Ill be buying an Alpine iDA-X305S (Single DIN) head unit, but Im not sure what mounts/fascias/braces/etc Ill need.

Can anyone list me the parts Ill need to get this mounted into the center console neatly?

Ultimately, Im going to buy the stereo components and brackets, and give them to an installer to get it all installed professionally.
The dash looks exactly like this one pictured:


Thanks in advance!
