hey there i was looking to get an navi for my tsx and was wondering if the portable is better then the oem navi or even the after market navi, i look at some and want to know what u think of these products : Plenio VXA-3000 7" Widescreen GPS Navigation System or Garmin StreetPilot 7200. Some of my friends r telling if i was to spend that much on the gps why dont i just get the aftermarket navi right but one thing about it is that i like how the tsx set up is on the bottom center concels, like i dont want to get rid of it, is there i way of just open that part that sides up and there u see ur dvd navi that can slide out, i seen some of u guys cut that part out its koo n all but i like to hide it.
