I was out driving around this morning with my V1 3.872 and it was originally working fine. I went to a grocery store and when I pulled into the lot, the V1 was going off because of the doors. However, when I came back out from the store, the V1 was no longer giving me a signal. I then proceeded to drive up and down several shopping strips in areas where I know I get signals and received no alerts. I ran the unit in all modes. I then pulled into a parking lot and ran a laser test by holding the unit in front of my Infiniti I35's gauge cluster. I do not know why, but when the cluster is dimmed, it always sets off laser and indeed, when I preformed the test, laser was working in all directions.
I am not certain as to why my unit would stop picking up radar and was wondering if there were any tests I can preform before sending the unit in for maintenance and upgrading. I believe the unit is running on factory settings and the unit has not been upgraded to 1.85. I am moving to Boston from Columbus, OH on Monday, so my unit could not have picked a worse time to malfunction.
(Typo made. The unit is 3.872, not 1.8.)
