Tried to install the update file MP77_UPDATE.CAB twice and got the error message "Not Enough Memory"

You don't because the magellan is having internal memory problems with corrupt files. You may try to update the firmware again but it probably will not work. Magellan Repairs are available at the jungleghost.com site.

I got mine back up and working by doing the following:
1st Icopied the files on the SD Card to my pc (for backup)
2nd I deleted all the files on the SD Card
3rd I went to the following link https://www.navigon.com/site/us/en/my_navigon/unauthorized/products_us

and download the update for Navigon 2100 and installed it.

Tested it and it no longer gives me the fatal error.

The easiest solution is to put an sd card (8gb or less) into the sd slot. Have Garmin Express install to the sd card.

You can also do a hard reset and try to install to the device itself. A hard reset restores the files to factory default, so it may free up enough space.

hi ;
this sems to be a memory problem;
in bios , try to decrease the memory for your card to resrve a memory space for the installation program,

if this does not work , it might be your VGA card.

have u tried the reset pin on the back? give that a go.

I don't know what program you're using, but usually when you get the message "An error message cannot be displayed because an optional resource assembly containing it cannot be found", it is because the program is using the .net compact framework but the file System_SR_ENU_wm.cab has not bee installed on the device yet. That .cab installs the resource file that is missing. Once it is installed on the device, you'll see a better error message than the one you're seeing now.

Thanks,
