OK I downloaded the IbycusUSA.exe file then installed it, and I see the IbycusUSA folder in my program files. That folder contains a tigerdata.img file, a tigerdata.tdb file, and a imgs folder full of .img files . But I can't seem to fiqure out what to do from here. I already have mapsource installed and I have a 60csx. I have never installed a map before.
