It seems to me as my x50 is more of a noise maker then a helper now a days.
I have a g35 sedan and i high mounted mines to the right of the RVM and right under the factory tint stripe.
I've had this radar for 3+ years. About a year ago when i got the g35 i've noticed the falsing to happen a little more often then my prev car. Highway this thing beeps all day long at random spots on the road. I've reset and currently running with X band off. When it does false its mainly Ka bands at FULL strength pretty much on and off.
I'm out of warranty obviously being 3 years. If i send it in for a update what is the price of that? If there isn't a simple fix for this i'm most likely going to upgrade to something. I've got my money's worth in the past 3 years.
