first to get the maps you have to download them over a wireless network connection or follow the notes on copying then to the rs-mmc card. has to be in a specific directory structure.

i had some trouble downloading the maps, and went through my network settings. i didnt change anything, but save the settings again, and all was well (other apps had trouble too and they cleared after). i do notice once in a while, that the apps seems to drop the network stack and i have to close the app restart/reconnect to the wireless network and relaunch the app.

the new OS image seems to have tightened up the networking a bit and it seems better now.
