I just returned from a weekend of driving a Hertz rental with NeverLost. It's basically the only reason why I will rent from Hertz exclusively.

I live in NYC and I do not own a car, so driving is not a regular activity for me, and I don't mind admitting that navigating around a strange location on top of driving is just a bit much for me to deal with. Given the difference between trying to follow the tiny dots and lines on a map and having directions spoken to me at a very intelligently measured pace, give me NeverLost anytime.

In addition, there are little prompts, like the little bits of information that you see on the screen when you're watching the news or sports these days, that I find extremely helpful. For example, it tells you what the next move will me (to the left, to the right, or straight ahead), how far you have until the next prompt, and also how far you have to you indicated destination. All extremely useful as you try and decide things like when to stop off for gas, food or occasional breaks, or when trying to decide when you will probably arrive at your destination at your current pace.

If I had one complaint, it would be the amount of time that it takes for it to re-calculate the route, either when you first set it up, or when you've veered off course, either accidentally or intentionally. Sometimes, when you're in town, you've got to pull over to give it a chance to re-calculate a new route from where you are now to your programmed destination.

I've never had an issue with it sync-ing up with satellites, even in town, although I will point out that on the Hertz vehicles, there is an antenna attached to the trunk, which I assume is a booster for the built-in antenna on the device itself.

The interface for entering information for your destination is a tad clunky, so I hope they've improved it in more recent versions, and the pacing of the prompts does take a little getting used to. I also find that it doesn't handle somewhat complex directions very well -- like when you've got an exit going into an immediate multiple merge -- but those instances are relatively rare, and it handles 95 percent of situations very well.
