So I'm taking the tribe on a driving trip to Florida. I'll be using the EVO for navigation. I can either use "MAPS" and enter a destination, or "Sprint Navigation". Is there any reason to use one over the other? Is there a free download that is better? I've used the Sprint one a few times, but it was quite annoying as it kept talking to me, even though it was saying to basically keep going on the road I was on. I'll be on I-65 for about 15 hours, so I don't need that crap.
