I put in my serial number and got this:
V1 Description: Radar circuitry known in-house as V1.8—POP1. This is our latest and best performer on both radar and laser with just one exception—its POP Protection has been superseded by POP2. Of interest to those who drive in Europe, the latest V1 version also has a Euro Mode.
Upgrade Recommendation: You already have a sophisticated security system complete with POP Protection superior to all other brands in the industry. POP2 is an evolutionary change, a part of our Continuous Improvement program. It reduces the false alarms from other detectors compared to the POP1 version of V1, and includes an addition to V1’s proven warning vocabulary. If you drive in Europe, you will appreciate our new Euro Mode which improves protection on photo radar as it is used in the E.U.
They want $139 for the upgrade. Wanted your opinions. Thanks!
