After being misdirected a few times with the ensuing confusion, she had finally commissioned me to update the maps on her GPS.
She delivered it to me and it has been sitting next to my PC for a couple of weeks now.
I think she means it this time.

Sometimes I think about updating her to a newer model.
But, we've been together off and on for over 20 years now.
I can't help but to think of her as being my best friend, despite her minor failings.
I'm hooked.

OK, I have made a backup of her favorites and the existing map set.
I have updated the firmware, voice and software via Garmin Express.
I have an unlocked copy of City Navigator North America NT 2015 in the form of gmapprom.img.
I believe I am ready to install it into her GPS.
Except:
The existing gmapprom.img file on her GPS is 1.09GB.
There is only 514MB of free space on her GPS.
The replacement file is 2.16GB.
If I delete the existing file there still won't be enough room for the new file.

My thought is to copy the new map set onto a 4GB SD card, erase the old file, then, install the card with the new map set.

Is this a viable plan?
YES! You Can Do THAT
