Hello, new member on the forum. I just ordered my new v1 and i couldn't be any happier. I previously owned an Escort 8500 for about 1 year and it served it purpose very well. I sold it and now i'm going to have the best. I have a few questions that relate to the v1. Can i use a regular phone cord and use that to power the v1? i read somewhere that regular phone cords have 3 wires not 4 like the v1's. that this will only take out the mute function. another question is that how can i dim the display so it wont be that bright when i drive in the night? thank you for your replies and i look forward to getting some more knowledge on rd's in the forum.
