I've had my 2011 Sonata Limited for a couple of weeks now. Here's my take on the Navigation system. First of all, I'm a techy guy. I've already got a couple of stand-alone GPS units, plus my Google Maps Navigation on my Droid (by far the best!). To put it simply, the Sonta's GPS system is BAD. First of all, it's out of date, and there are no updates (called Hyundai Customer Service). You can go to the company that makes the software (can't remember off the top of my head, but it's list in the nav manual). They make Nav software for Hyundai and Kia. If and when they do have an update, it's $199 !! But back to the Nav I already have. First of all, it's buggy. Twice it's gone into infinite loop which the voice repeating a direction over and over and over. The fact that it's a 2D flat map is also not good. All the other GPS provide a "birds-eye" 3D look, which is much better. Maybe I'm just not used to it, but when entering in an address to go to, I would think you would want to enter in the CITY, before the actual street name, so it gets narrowed down fast. Seems bizarre they list 147 "Main" streets (you can select the "Advanced" button to enter in a city first). Now I admit this works fine if you have the only street named BLAHBLAH in the current state, but otherwise, you look at lots of street names and drill down from there. But I do like how they eliminate impossible alphabetic letters as you type. Directions wise, I simply don't understand why it does certain things. We all know that GPS units may not make the best choice, but when we are out of town and don't know better, who cares. As long as it gets us there. Locally, however, we know better. Some of the directions it's given me for local routes are just plain weird! But its "rerouting" procedure is even stranger. Normally, if there's more than one way to get somewhere, and you take "the other" route, after a short while, it gives in and reroutes your way. This thing, on several occasions, has INSISTED I continue on it's original route, even when I'm a long way past the point of no return. A couple of other things: seems to only change to "night mode" when you turn on your lights - not based on the time of day. The giant split screen showing you the next turn, at the expense of the overall route, seems overkill. It already showed you the turn icon you will be making. The "turn-by-turn" directions, list from bottom up, seems weird to me also. And you can't slide the slider bar down. Gotta touch the down arrow, one-by-one. Also, can't seem to adjust the volume level of the voice. Either on, or muted. It is not controlled by the radio volume buttons. And trying to "scroll" the map by putting you finger on it, and sliding. What an abomination. First of all, seems to scroll in wrong direction from what all other interfaces do. Other things: when I press the Home preset button, take me there. Don't ask for yet another "set as my destination". I already said I wanted to go home!
