Which one? They offer several. For every GPS product you will need to load a GPS application of some sort and the maps as data files. With the X30 you will get about 30M of Built in Storage. That is over and above the 64M of RAM that is divided between storage and program execution space. It's like a built in flash card. If you don't go nuts you can load a significant amount of programs there, like the mapping application.
Map sizes vary by program and area covered, but you can figure decent map files will be in megs or several megs. Those would be counties, or metro areas. Things of that nature. If you only load a few apps in Built-in Storage you can get away with keeping a few map files in there as well.
You are going to be wanting a storage card at some point in any case. I expect maps aren't the only things you are going to want to keep with you, once you get going, and you will rapidly run out of storage space in that 30M. You want to try not to burden the 64M to much with storage as some things have to go there, and the more you can leave open the better things work. Just like a PC, more free RAM improves performance.
Anyone use lower end GPS Unit ?
