I've been using the Redline since May 2010, and I noticed recently that it will not detect some road speed signs. I have driven past those speed signs with it displaying my speed but my Redline is completely silent. I'm not sure if the Redline is failing or not, but it does give some concern.
However, my Redline has detected everything else, including pharmacies and such. I have had a Massachusetts State Trooper speed past me but the Redline blared full blast all of a sudden in K Band right after he passed me. Does it not have good ramp up? I know the trooper has had his rear antenna on the whole time. Does anyone have an explanation for this? I hope it's not a problem with the Redline.
