I am not replacing my new V1 (that will never happen), but my son was in town from college for the night & has a 4 hour drive back to school tonight.
I realized it would be a good idea to get him an RD for his Acura TL, but I think he will be better off with an 8500 for a few reasons. My son will never mess with the programming like I will, he will simply plug it in & go. He also would not have much use for an RD that falses too much, if the RD started doing that he would either turn it off or simply ignore it.
We bought the 8500 from Bestbuy for $300 & then used it in my truck all day today to try it out. It only went off once, but that was a for real alert on a Ka band blast & it ramped up perfectly (totally unlike the 9500i I got to try for a while) & gave a good mile or more warning.
I was totally impressed with the new unit, I still like my V1 better (mainly because I love the modified hidden remote) but I would certainly be very happy with either choice.
