I found a number of iGO8 R3 (Navteq) 2015 Q2 maps and poi files, but am not sure they would work. poi files seem to have 130724 except for Canada, which has 130828) There is also an 'extended' file for most of them, such as: poi files seem to have 130723 including Canada) fbl files seem to have 131004 in them except for a few with 131017) The sub directories on the card align with iGO sub directories I've read about here, such as content/map, content/poi, etc. The file version is 9.6.5.0, the product version is 9.67. The icon for it says iGOprimo, so I'm presuming that's the system I'm using. I copied the SD card from the radio, and it has an 'RTNavi' directory, which contains a main executable called Mobilenavigator.exe. I'm wanting to update (USA maps & poi) again, and have been reading a number of threads here and elsewhere. I know the used radio had no SD card when I bought it, and I had to download a card file to get it operating. I have this radio and had installed some map updates over a year ago, but I forgot how I did so.
