update: i was able to get me another psp, pandora battery and cfw 3.71 m33-4. i installed MapThis! on the psp and loaded my maps. took my car for a test drive but couldn't get it to work. came back after 5 mins figured i would do some more reading. i started playing with it again and notice that it had a fix on my position while i sitting on my couch. i will take it for a test drive soon.
thanks for everyones help...

okay, after a few days of enjoying the gps. i have a couple of questions.
1. is there any way to set the zoom level on maps. e.g. i have an area that i want to include but the zoom level is either too small or too large.

2. i have created several maps for my area, is there a way to combine these maps so that i don't have to reload each one for the cities i'm traveling through.

3. after i created my maps and have use them, is there a way to go back in gmdl and reload the maps so i can add more zoom levels. i didn't include them the first time i made the map to cut down on size but now i want to add them back.

thanks...
