The only thing I don't like about GPS Systems is that when you pay all that money for a GPS unit, the software updates should be free of charge. The software that's in my unit is out of date but only a year old and I have to shell out another $75 for the new software so I'm up to date. I didn't realize that nor did I asked the question at the time of purchase. Just a good FYI for ya.
I have a Garmin 330 Street Polit. It works pretty good. If I type in the name of the campground in the right category, it will come up on the screen with the full address and with the option to start to "GO" or see it in the screen. https://buy.garmin.com/shop/shop.do?pID=6385
There are so many to choose from now a days. I guess it's all about how much you want to spend and what you want the GPS to do. Do your research and look up some reviews like CNET at http://reviews.cnet.com/4244-5_7-0.html?query=GPS&tag=srch&target=
I always go to this site before I buy anything. I like to read all the useres reviews to get a feel if the product is really any good. It's saved my rear a few times.
I also have the Garmin Steet Pilot (Sams club BlackFriday purchase). I really like mine. I believe that you can do a search for parks on it also. I mainly use mine by inputing a address and letting it find it. We recently took a trip to New Orleans and the little lady took us there and back with not problems.
man, I didnt realize that about the software updates. I agree, that should be free. That Garmin 330 looks pretty nice, I go look at it. I have used cnet a good bit before too, I am going to go through all of their reviews and then pick a few to check out. thanks for the info.
I should clarify that I'm talking about the map software. I have road maps for North America dated 2005. The new 2008 map updates are available from $70.00 to $100 depending where you go. There is another software that make the unit run, I guess the operating system that allows you to turn the system on is a different one and is free I think just once. I guess like any other computer software, like MS Office, you need to buy their new software when a new version comes out. Arguably No difference I guess.
I use Google Earth to look up where I'm going because it's real images and I can see whats around the locations I'm going too. I really like the GPS for other reasons like gas stations ATM Machines and restaurants if we're hungry. I use it for those reasons more than anything.
