My Garmin StreetPilot 2730 won't hold its settings.
Do a hard reset.
Turn the unit off, then hold down
the menu and map buttons, simultaneously, then turn the unit back on
and continue to hold down the buttons down for at least five more
seconds, then the unit will power up. At that point it's like the unit
is being used for the first time and you will have to reset everything.
You will lose your XM presets, but the MP3's were still there.
Also after if this does not work, plug in your
garmin and mount it, mac or pc whatever, then go in your garmin file
erase all maps should be gmapsupp.img or gmapprom.img. Reload your maps
from mapinstall.
