I meant to post in this thread a ways back but forgot. Two things make me remember why i don't regret getting the V1. First the arrows. Awesome and it's the only one that has them. And they work. Second, the remote display. All the other remote displays are attached to the cigarette lighter, while the V1's is removeable. Which allows for mounting right in the gauge cluster, which is what I did, while hardwiring the detector up by the mirror. Nice and clean.
