I can't help you with the head unit. Go to their websites and see if you can see the rear connectors, or download the manual. 

You need to go to a company like Autoleads. The following is their e-catalogue

You need the double din face plate adaptor, look on pages 107 to 109 for the part numbers.

For the steering wheel adaptors and wiring to fit the JVC, Kenwood(Keyword?) or Alpine, look on page 110. PC99-209 stalk adaptor, PC2-17- 4 Toyota ISO harness adaptor.

With the info above, you should be fine.
