So after my experience switching from the Redline to V1, I personally cannot live without the arrows now. Just picked up another V1 for my gf as her X50 is acting up.
Hardwired it and put it high behind the RVM, her first reaction was "EWW what's that thing, so ugly!". I was thinking to myself "Damn girl you have no idea how luck you are ".
I briefly explained how to use it to her and took her out for a test drive, she couldn't stop complaining about how ugly the V1 is. We stopped at a red light on a big intersection, next thing you know, V1 goes off Ka alert, nice ramp up and arrow points ahead. I knew she was impressed when we both saw a local LEO drove pass us and we watched as the arrow changed from front, side to rear.
I then half jokingly said "OK if you don't like this ugly thing on your car, I will return it and get you another Passport"
She said "No, I guess this thing is alright..."
