Thanks for your inputs. I am not excited about paying the price for these systems but i really don't care for the detectors in the windshields. I know that some people hard wire the V1 detector above the mirror and place the remote display down in the dash area and even with the laser diffusers would be cheaper but I feel that the SR7 would be a better look and it is highly rated. I am currently leaning toward this unit but I am still researching the Calibre system. I haven't heard from anyone on this forum who has one.
