Thanks to the efforts of everyone on the forums, we now have a fix for the dreaded blue/green boxes that show up when no route is active in the factory software.
Before/After:


There are two ways to apply this fix:
1) Download the prepackaged DATA.zip file and install it on your system. This is by far the easiest way, and that is how I would recommend novices perform the installation.
2) Manually edit your navigatemap_800_480.ui file if you already have customizations to your skin that you would like to retain.
Option 1: Prepackaged Installation
This is the easiest way to perform the modification, but should not be done if you have already made changes to your skin that you wish to retain. To install, download the DATA.zip package at the link below and install in the following directory using the TESTMODE mod:
My Flash Disk/APL2/iGo/
I recommend you copy your existing DATA.zip file found in the above directory so that you can restore it just in case something goes wrong.
Download DATA.ZIP (6.1MB file)
Option 2: Manually Edit navigatemap_800_480.ui
If you have already performed customizations to your navigation skin, chances are you have an altered version of this file. In that case, you will need to manually perform the edits listed below on the appropriate lines in your file. This file can be found in:
DATA.zip/ui_pioneer/800_480/ui/
Line numbers below are given for the original file, so if you've changed things, they may be in slightly different locations.

Save that file to your DATA.zip archive, and install on your F-Series and you should be set.
Enjoy a clean map when no route is active!
