Mine is a 3.863 bought as refurb from VR 5 years ago.
The main display is not working properly. The only thing on the display that works is the bogey counter. The rest will stay blank (or very faint flashing if you look hard enough) even in programming mode when the entire display should light up nice and bright initially. My V1 is getting power from the cigarette lighter outlet at the center console. My car has fuel saving engine stop/start feature and I wonder if too many ons and offs during rush hour traffic will kill the V1 since the outlet is switched. Is there anything I can do to troubleshoot the problem before sending it back to VR for repair? Thanks!
