As far as I know, the only thing that changed from the v1.8 which I have to the current one is basically only app integration. The sensitivity to the signals is the same. (valentine doesn't recommend the update)
This is what it says when I put my serial number in:
V1 Description: Radar circuitry known in-house as V1.8.A-POP2 with
Euro Mode.
Comment: This is our latest and best performer on both radar and laser.
Upgrade Recommendation: You already have our best performer, enhanced by crystal-controlled frequency tuning. More recent V1s, however, have two additional features. Traffic Monitor Filter eliminates the K-band false alarms caused by a traffic flow-measuring system being installed along some U. S. highways. SpeedInfo sends frequent K-band radar bursts into the traffic stream (
www.speedinfo.com to learn more). If you drive in an area with one of these systems, this upgrade will pay off immediately. Extended Serial Protocol (ESP) enhances two-way communication with SAVVY and future peripheral devices.
Our V1.85 Upgrade* for this series of V1 will produce the following benefits:
Traffic Monitor Filter eliminates false alarms caused by SpeedInfo, a traffic-flow monitoring system that sends frequent K-band radar bursts into the traffic stream. For more information,

Extended Serial Protocol (ESP) enhances two-way communication with SAVVY and future peripheral devices.
*One-year limited warranty starting at upgrade date, same as new units.
-- Upgrade to V1.85: As soon as we receive your old unit (in operable condition with no tampering of the serial number) we'll replace two circuit boards and install revised firmware, then return it to you in the shortest possible time with a new serial number to indicate its revised capability.
