I've had my new 9500i for about 2 months now and so far so good. I do however have one thing that I find frustrating with the radar detector. Whenever I get hit with any band of radar (X, K, Ka, ect), all I hear for the first couple seconds is the noise of whatever radar it is picking up, it does not show me what radar band it is on the screen for at least around 2-3 seconds so I have no idea what I am being hit with unless I remember the exact pitch of noise that each band of radar makes.
My friend noticed this as well, and he said that he does not have this problem with his 9500i. Perhaps I have an older version and there is something I can do to fix this?
