I'm with Nelson. The entire US at all zoom levels is something like 100 gig. My suggestion is to only do the zoom levels starting at 16 and going down to 6. You'll almost never need 4 and 2. At least that's been my experience, and before getting my Garmin I used MM via my NIT a LOT and not once did I ever find a time when anything below 6 was either necessary, or practical. I do have a zoom of 4 for Las Vegas, but that's only because I needed the fine grain detail for city navigation, and that's about the only place I have it for, save for a couple small towns up here in Michigan.
But if you want to download them, I recommend actually doing it on the PC. You'll first want to get the download script and information on usage in this post here and then install everything you need.
Next, you'll need your four GPS markers to set the range which getmaps needs to grab the data from. To do that, go into Maemo Mapper, zoom and navigate to the area you want to download, then click the menu, maps, manage maps, then click the second tab. It'll tell you your coords. It should be labeled "area". It's not the top four numbers you want, but rather the bottom four, and you want them exactly in the order they appear. They'll be top, left, bottom and right.
Next, type this on the command line:
getmaps GStreet.sqlite -t 44.86000 -l -88.43000 -b 39.83000 -r -81.62000 -z 16 -z 14 -z 12 -z 10 -z 8 -z 6
Now let me break this down for you so it's understandable. getmaps is the command that runs this script. GStreet.sqlite is the database you'll be building for MM. -t, -l (that's a lower case L), -b, and -r are the top, left, bottom and right coordinates respectively that you grabbed from MM. The repeated -r ## values are the zoom levels. Doing the even numbers from 16 down to 6 is all you'll need. The total build time for this will be about 7-8 days under ideal conditions. 2 weeks or so if things get bumpy.
Just a word of warning. You might want to toss that command line into a simple perl script or use some tool to restart it automatically when it exits, because it will exit about every 10k-20k tiles. Sometimes as often as every 2k-3k tiles. This is not a fault of the script, but rather python itself since any tiny dns hiccup will cause it to fail and exit. An automatic restart will do the job. Just be sure you have some kind of ability to break the script once it's completed all of its work.
The total database I built came to about 7.9gb. It contains all of the even numbered zoom levels, from 16 down to 6, plus a zoom level 4 for the Las Vegas area (I was planning on using it for CES this year) and a couple other local towns in Michigan. If someone's got a place to park it and doesn't mind hosting a nearly 8gb file, I could be a sweatheart and save a ton of work for you guys by uploading it so you can grab it without having to build your own.
The other option is bittorrent, but I don't have an open tracker to use. If someone has that, I can just toss it on Bittorrent for everyone to grab. From there you can modify or customize it to your liking. The build is dated the 14th of August, so it's still pretty current.
One last thing, to install it you'll first need to copy it to the tablet onto your external SD card, as it's too big for the internal cards. Then you'll need to go into Maemo Mapper, make a new repository from scratch, select sqlite as the database type, name it "Google", specify the path to the db, and the db itself, and then save it. From there it should load without a problem.
Hope that helps.
