Aftermarket Radio questions

[Seshmaru]

So I have a Berlingo Multispace 2007 80kW, and I bought a Pioneer DEH-S420BT, had some trouble at first with the memory part, but switched the Yellow with Red and that seems like it solved the issue..
EDIT: also the stereo wont turn off when I pull out my keys.. not sure what I am missing..

My main question is which adapter would be ideal for this model from Connects2? the prices vary and the "universal" adapter costs more than the designed one..(I am from Europe)

Also the second issue I've been having is the center display, it freezes the time as soon as you start the engine, but doing some more research on this, seems like disconnecting the battery for 30sec seemed to have solved the problem for some people.. 

and well the last question would be upgrading the central display.. but not sure that is possible.. Ideal plan would be a Android GPS or such.. but I can't really complain..

Connects2 have a technical department that was responsive when I needed some help selecting what parts I needed a couple of years ago, link on their website

I wrote them on Facebook, since that was an option as well, thank you!

EDIT: Facebook and Instagram had the same response to write a ticket to them, and I have just received my response with "CTSCT002" since the original stereo was RD3, also CTPIONEERLEAD or the CTMULTILEAD.2 is required.
