I just took a trip from Norman to Dallas yesterday and 2 hours into my drive my V1 gave an "E." I was like what the heck, this shouldn't happen so soon. So I turned off my unit and turned it back on and drove it for 4 more hours total and it didn't show up again. I didn't speed since I was skeptical about it although it alerted to speed signs perfectly well and one other LEO on K band. It doesn't seem like my V1 gets good X band. I'm not sure.
Does anyone have any thoughts? I'm for sure sending it back into V1. I just got this two days ago but it is a refurbished unit. So maybe that is why. And I also did not leave it in the car or in the heat. I brought the unit in with me.
