Hello Am relatively new here, owns the V40 T2 BJ. 2001 only for a few days. Would you like to change the antenna, I have to solve the sky? Is the “original antenna” fixed up? Have a Kenwood double-din installed, everything as far as OK, now I also want to install an R-camera. It is a fixed installation, 25mm diameter, doesn’t know yet exactly where to place you? A question about it, do I need a signal for the camera (not the video signal) at Kenwood there to the return lights? or is it easier, front area of the vehicle, at the relay or so, schematics available here?
