Navigation system
First, let me say that I LOVE this feature, being navigationally-challenged. Which, in L.A., is a hindrance to getting...anywhere.
Second, on my first use of the system (after the previous owner ran me through a 2-minute crash course), it led me straight to my destination, a place I'd never been before in a neighboring city. "Great!" I thought. (I figured I could get home unaided and, of course, got lost, but that wasn't the system's fault.)
Then I tried to go from L.A. to the San Diego Convention Center. This trip is so easy, even I can do it from memory: 405S to 5S, exit at Front Street, take Front to the Convention Center. But when I tried to take The Control Voice's directions, it immediately had me exit the 405 freeway. "Screw that," says I, and I turned it off. On the 5 freeway, I tried again. Again, the Voice suggested that I get off the freeway. "You're nuts," I replied, and turned it off again.
Attended the convention, drove around S.D. a little, decided to head home and figured the Voice would take me to the 5. Instead, it had me following a twisty-turny route through the city, during which I actually drove OVER the 5.
Then it dawned on me: the previous owner had said he hated the freeways. Sure enough, he'd programmed the system to drive around all freeways, and it was trying to route me between L.A. and San Diego over surface streets, a route that would have baffled Lewis, Clark, and Sacajawea.
Once I de-programmed it, it performed flawlessly.
Third: The system is about as non-intuitive as an old DOS computer. Yes, you CAN delete destinations, but you'll go through several menus and have to hold your mouth just right to do it. Consult the manual, which I would do for you but it's in my car, in the garage, and I'm lazy.
