Although LeetLauncher is not perfect yet, but the good thing is, you can leave you F500BT untouched, just run everything off the SD Card.
Read thru this thread, if you want learn more about LeetLauncher teaking:

This is the short path to start:
I also cleaned up the speedcam.txt that comes with LeetLauncher 3.0, otherwise. it's going to take about 7 minutes to load all the NorthAMerica and European speedcam info from the text file.
Extract DEM, MAP, POI, BUILDING files from the torrent 3.0 package and copy to your SD Card to \iGo8\Content.
Put the SD Card into your F500BT, do a hard reboot. it should work.
BTW, I also put the generic world license file + the license file from the 3.0 package. This should not matter as LeetLauncher already comes with a license file.
You can also download the latest igo8.3.2 executable PNA version from other forums,I tested a few builds, they all work well.
