Just started looking at the individual .img's in my original install folder. I ran gimgunlock on one of them and it said XOR not 0, fix it first. Well, all of the img files are the same. This must be preventing Mapsource and Homeport from picking them up even though GarminUnlocker said all was unlocked. Hmm....I will have to run gimgxor on all of them and see what happens!
Update - Well I did that and no difference. Mapsource and Homeport don't see anything except that vertical yellow area I showed in the post above.
