| The units are nice, the thing is though, Installing the NAV unit in a visible spot is sort of like asking for trouble. The Drive out has a detachable bottom faceplate, but the nav unit has no theft deturant system at all. Around here, people will steal Anything, and I do mean anything. Plus, once you load the DVD into the NAV unit, there should be no reason to acces it regularily, its just a 1 DVD unit with a $150 new DVD every year if you want... Just my 2 cents. I install these things for a living and I see people comming back all the time who just weren't smart about where they put things. I'm always cautious though, I'd hate to have you get an expensive NAV unit stolen, you know... Just my $.02 |
