I also have a 60csx and utilize both those programs on my unit. The exact versions you want are TOPO U.S. 2008 and City Navigator North America NT v8. I have all of California on my unit because I used it to travel from No Cal to So Cal recently and it was fantastic. The City Navigator can give you exit locations, restaurants, gas stations, etc as you are driving. I have them on a disk and loaded them onto a 2gb micro card. Initially my unit came with a 128 mb card, which was fine for my home county, but when I added all of California it wasn't big enough.
