Well after a hard day traveling comparing performance of the V1 versus RX65.
They were 3 feet 9 inches apart too help reduce any problems between the two.
V1 Option 5 was set to Ka more responsive. All Bogie Mode
RX65 set to Ka USA mode. Highway mode
This is what I have found.
V1 Fantastic K range 1-4 seconds faster and 2-6 seconds longer than the RX65, V1 rear ant there for ya.
V1 Fantastic X range (when I enabled it)
V1 J'ed out a false radar signal RX65 also alerted too.
RX65 alerted 4 seconds before the V1, versus a 33.8 Bee III.
V1 stated quiet against some Ka sources that the RX65 alerted too.
V1 J'ed out real instant on 33.8 Bee III radar source?
V1 failed to detect third hit from one true Ka radar source, it then did on the forth hit (see above) and continued to stay quiet until reset, RX65 was alerting every time, good work.
RX65 falsed alerted POP from a signal then it alerted, V1 gave one Ka beep then J'ed it out. (This was good for the V1 ) This was a junk detector from the car next to us.
RX65 alerted Ka falses more often, you would see this in USA mode.
I am now torn..
I would say they complement each others weaknesses.
What I am not happy about is the V1's Ka detection.
