I had the 9500i before and it used to have this feature where you can mark a location so that whenever you approach this "mark location" it will alert you. The 9500i will alert you 5000 ft when you are traveling more than 50MPH and 2000ft when traveling below 35?MPH. this was a good feature. I liked it.
But for the 9500ix, since it has a database of a lot of red camera, speedcam, etc.. it has reduced the alert distance from : when traveling below 35?MPH = 500ft, more than 50MPH = 1200ft.
the manual shows:
red light cam = 250ft or 10 secs
speed cam = 250ft or 10 secs
speed traps = 1/3 mile
other = 1/3 mile
it could have better if the distance is exponential according to your speed, faster travel = 5000ft alert, slower travel = shorter distance.
with the current 9500ix distance alert, which i just found out today since i just got my 9500ix, the alert me distance is too-short. traveling at 70MPH, 1400ft alert distance is too short, I can already see the LEO with a big smile and writing the speeding ticket already before the "alert speed trap location" warning.
I hope there is a tweak around this feature...
