I owned a Passport X50 for 4 years. Loved it. Saved from more than a handful of tickets. When I bought my X5, I thought of it as a chance to switch to the V1, mainly because of the directional arrows. I would have to hardwire a RD once again, so I figured it was a good time to switch. I must say that I have been very pleased. The range on it seems to be slightly better than the X50. I went through and programmed my V1 to my custom settings. The arrows have been awesome. This was the main reason I wanted to give this RD a shot. Not only do I get a warning now, but I know what direction it is coming from ! All in all, it has been a great couple of weeks. My only negative is the pre-historic design of th darn thing. Looks horrible to the naked eye. I really wish they would update their look. But besides that, I'm a happy customer !
