How to wire Sony WX-GT90BT in VW Sharan 2007?

Hi, I would like to replace the RDC 200 from my VW Sharan 2007 (European model, I live in Europe) with Sony WX-GT90BT. My problem (I'm a novice) is that I don't know how to wire the Sony WX-GT90BT, because it has a different connector compare to RDC 200. My questions are about the power connector and not about the speakers and not about the CAN bus. I will use an adapter to do the connections. In the Sony-WX-GT90BT installation manual (http://www.manualslib.com/manual/445773/Sony-Wx-Gt90bt.html#manual) there is the power connector described: 1-not used, 2-not used, 3-not used, 4-yellow-continuous power supply, 5-blue/white striped-power antenna/power amplifier control(REM OUT), 6-ORANGE / White-switched illumination power supply, 7-red-switched power supply, 8-black-ground In the RCD 200 wiring diagram there is the power connector described: 1-not used, 2-CAN bus+, 3-not used, 4-CAN bus-, 5-+U (thick, red), 6-not used 7-+SAFE (not thick, red with white stripe), 8-Ground The only one obvious (for me at least) is the 8-black-ground. I mean from the RCD 200, I will wire 8 to 8-black-ground (Sony). I checked with a multimeter and 5 (RCD 200) is the continuous power supply. (I removed the fuse for the factory radio and 5 (thick, red) didn't had any voltage, so this one is intended for the radio). With or without the radio fuse, 7 still had 12V. With or without the key, 7 still had 12V. Of course I'm talking about the RCD 200. 1. Is it possible that the factory radio doesn't need a dedicated switched power supply and a switched illumination power supply because it's getting this information from CAN bus? 2. Where can I get a switched power supply and a switched illumination power supply for Sony? 3. If I will connect just 4 (yellow-continuous power supply) and 8 (ground) to Sony, will it work? I will have to turn it on and off manually, but will it work? Could someone please help me? Thanksadrianpop81
