You know the V1 does not implement software in there radar detectors to defeat the Spectra III or Spectre Mk IV +. Since radar detectors are only illegal in washington and virginia I can see why most of these company's really aren't as concerned. But it is interesting the results you got
Remember you have to compare apples to apples. Use two radar detectors that have this feature to defeat the spectra III. No disrepect towards you, but I've only noticed the Bel Sti has this feature. Do the cobras or whistlers have the same software that the Bel sti has or is the Bel the only stealth to the spectra III's??
