Got it! Thanks for all the help guys. I ended up using a program called IconDeveloper by Stardock to convert the .png to an .ico (so it maintained the transparency). Then I used another program called Icon Changer to change the embedded icon in Garmin Mobile XT.exe. Looks so much better.

See attached zip for the exe with the improved icon. Just replace:

Phone\Garmin\Garmin Mobile XT.exe

with this exe and then soft reset. All shortcut icons should update to the higher res icon. I've also included the .ico file just in case, but you shouldn't have to use this.

Hope this helps others as well!
