The 480i 's IVT is a joke, and for the release date they had on it, hasn't been updated. It is either alerting to K or Ka band on Honda/Chryslers and even road side traffic monitors. Can't even turn on or off filtering, only change the "Sensitivity" mode.Had the 480i. Was getting an insane amount of false alerts. Switched to the new Escort Max 3. A lot less false alerts and just seems a lot better.
