Problem retrofiting a newer TravelPilot NX and BT/VC Module

[Heinrich]

Hello I'm Nuno from Portugal and I appreciate you hekp with the following.
When I bought my 2008 S-Max it originally came with a Sony Radio with BT/VC. 
After a while I retrofitted it to a TravelPilot FX, and it was plug and play. After some time I changed the FX for a 
TravelPilot NX and it was also Plug and Play. A few weeks ago my wife started driving the van and told me she wanted a 
reversing camera, so I had to change the NX for a newer NX with video input. 
The radio is from a 2011 van. 
I intalled the radio and also changed the BT/VC module for one with USB and Streaming.

Now I have two problems. 

1 - My cell phone connects to the system, but when I make a call, I hear noise, and when I stream, nothing is heard.
2 - I have some radio keys without lighting.

 

Thanks in Advance

Best Regards

Nuno
