Car: O2 2007 Combi

I'm planning to swap my Stream radio with an aftermarket Sony radio. I know I need a phantom adapter for the antenna. Got that figured out. I also bought a 1-DIN frame + new dash panel of eBay.

I'm struggling however to find out which adapter I need to hook up the radio. My regular supplier has two on the website. Can somebody tell me the difference between these two? The second one is a lot more expensive. BTW: I don't have steering wheel functions on my O2.

Adapter number 1

Adapter number 2

think you will need adap 2 as otherwise you will have no ig control of the radio. The box is the CAN bus decoder.

As above you need the 2nd one unless you want to find a switched live in the fuse box and wire it up to the ignition live on the head unit.

Thanks guys!
