Seriously Abb, got some time for an Ottawa fan? I'll ply you with brew if you'll help me install your mod. 
Too easy, just follow the directions to a 'T'! It is easier than it seems--
Extract all of the folders/files from the .rar file you downloaded, onto a freshly formatted SD card with a testmode folder. You only need to deal with 4 different folders on your AVIC and they are labeled on the folders themselves that the files are in within the zip once extracted.
Also make sure you have a full back up of your FLASHDISK. Really, you are going to edit a lot of files here and it will be nice to go back if you want/need to.
Once the SD card is inserted into your AVIC, power it on and boot into testmode:
1. Click Start - Programs, Explorer then click on SD Card
2. Click on Start Again - Programs - Explorer then click on My FlashDisk - you should now have 2 Explorer folders open in the quick start menu at the bottom of your windows screen.
3.Using the SD card window click on the folder called 'put ALL CONTENTS IN 'MyFlashDisk' folder'. Move the 'System' folder found inside into 'MyFlashDisk' along side APL, APL2, etc..
4.Using the SD card window click on the folder called 'put ALL CONTENTS in 'MyFlashDisk-APL' Folder'. Move ' CommonLib.dll', 'Image.res', 'MainMenu.exe', and 'SystemSetting.exe' into the APL folder
5. Using the SD card window click on the folder called 'put ALL CONTENTS in 'MyFlashDisk-APL2-IGO' Folder'.
6. Scroll your pointer over the 8 files titled "bnt.ttf", "DATA.zip", “BULLPEN3D.ttfâ€, “Digital.ttfâ€, "DS-DIGI.TTF", "TAHOMA.TTF", "TAHOMABD.TTF" and "sys.txt", as well as the 2 folders, "3DCars' and "Extension" to select them all. If you are running an F500, or are using a unit in the EU, then edit the semicolons at the top of the sys.txt file before copying them over to the AVIC.
7. Go up to EDIT at the top window click COPY
8. Go to the FLASHDISK explorer window at the bottom of the screen and open it
9. Navigate to APL2-iGo
10. Click EDIT at the top window and PASTE all 8 files and both folders
11. When the prompt comes up asking you if you want to change files click the option that says "YES ALL" wait for it to copy files (because you made that backup right?)
12. You need to delete the user files so that your settings are built fresh with these new mods. They are in “My Flash Disk\User\UserData". Delete the ENTIRE "iGo" .
13. Power off your ignition to turn the AVIC off.
14. Pop out your SD CARD and then power back on to restart AVIC. DO NOT REMOVE THE SD CARD WITHOUT TURNING OFF YOUR AVIC FIRST!!!
