i was working down the street from the Valentine office, and picked one up. when i opened the manual there is an addendum that states:
"This V1 included an advanced technology that provides warning when speed radar is used in the POP mode"
"How to identify V1s upgraded to two-band POP
V1 powers up with test sequence of warning lights and sounds. At the conclusion of the test, just before the mode indicator appears in the Bogey counter, you will see a sequence of "P...o...P" on the V1s with two-band POP coverage"
someone on NASIOC called the Valentine office and confirmed, that yes POP is now supported, but they don't have the upgrade in place yet.
