I get many questions from members who want to be able to use single program content for other iGO programs so that they can save space. Here are the sys.txt entries to make to accomplish that. You want to put those entries in the other iGO programs. Notice that the content in this example is situated in the iGO8 program. Igo8 uses Loquendo voices so you would delete that bold entry to use in Primo 1.2 and higher since Primo uses NUANCE voices.

[folders]
has_secondary_root=0
sdcardpath="\Storage Card\IGO8"
maps="..\..\IGO8\content\map"
dem="..\..\IGO8\content\dem"
buildings="..\..\IGO8\content\building"
poi="..\..\IGO8\content\poi"
voice="..\..\IGO8\content\voice"

Obviously, your SD card may be named something else.
