I bought the XTR 690 and have had for a little while now not real long. Mostly have used it when going back and forth when doing errands and stuff. I will be going on a 2200 mile trip here within 8 days or so. I let you know when I'm leaving. I will give you a full report of the xtr 690 and how it performed at high speed :wink:
I do have a CB in my car so I know thats cheating a little. But heck I have found sometimes the CB to be better then any radar detector or laser jammer at times. Although I will still keep a strict sight on how the xtr 690 is perfoming.
