Yes, I believe the West/East coast Grocery POIs will do great. Currently I have a ONE LE with a built in 1GB, but I am running out of memory space as I type this. It does support adding an external SD flash card, but then I would have to run the entire map feature through that (I guess).
During my NYE's trip, I also recorded all the local Grocery stores in Valley Center, California 92082 (there are not too many stores there, but they are so scattered around, it is nice to find them when you are there in that mountain wilderness (Hey if you visit, you'll see some cows just grazing along! Makes a great Road Trip scenery).
