Prior to getting my AVIC-N1 I had the roadmate 700 in my VIBEI took the flex mount and bent it so I could keep it as close to the headliner as posible. I then put it up and to the left where you would have your oil change sticker. I thought I would have GPS signal problems but with the antenna where it is I had no problems at all, the only thing I didnt like was the power cord you would prob want to hardwire it.
