I have a 9500ix, a Redline, and a pair of M27s. I am thinking about trading the Redline and the ix in and getting a ci. It would just be cleaner and I would then be able to utilize all technologies. I just want to get some feedback on where to put the radar head, and the zr4 shifters. The heads may be useful to fill in some holes left from the m27s. Ill post a picture of the front of my car with the m27 heads highlighted so we will have a better idea on where to put the zr4s.
