I was about to buy this used v1 but when I called VR and gave them the serial number, the lady there told me the serial number is not in their database.
SO pretty much they will refuse to service it
When I entered it on VR's page it told me that it was 1.8 and that the upgrade price was 140 dollars.

V1 Description: Radar circuitry known in-house as V1.8. This is our latest and best performer on both radar and laser with just one exception—it lacks POP Protection. Of interest to those who drive in Europe, the latest V1 version also has a Euro Mode.
Upgrade Recommendation: You have a sophisticated security system, and we’re cautious about recommending an Upgrade. If you believe in keeping up with technology, particularly if the POP Mode is being used in your area, then go ahead. V1’s approach to the POP problem is superior to all others in the industry. 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.
