In your opinion is it worth getting the cheaper garmin or magellan and downloading the data required or just get the better one?

I have had the Garmin GPS V for a couple of years now and it does what I want. Very good detail and it's mounted on the dash, but I also take on my four-wheeler and use the Topo maps when checking out new land. No color or anything but has been one of those things that gets the job done and haven't thought about upgrading it.

I just moved to Indiana and that is the push behind my interest in getting a GPS. What do you think, is it worth getting? I just figured it would be easier then a map. But some people have told me that a GPS might not be worth the trouble.

does any one know where do they mount the factory GPS antenna? I bought the factory GPS with antenna but can find a location where the original antenna should be. Thanks
