I have a Satnav which has out of date maps. The old maps are IGO. The satnav was retro fitted and the people I got it from always provide me with a download link for new maps when I ask, but I never get any instructions. I have downloaded a file and extracted it, and now I seem to have NaviOne maps. See screen grab for what is on my old 4GB card (on the right), and the new stuff I've download (on the left). My question is this: Do I strip out all on the old card and put in all I downloaded? Or do I leave some bits? Do I just switch Igo.exe for NaviOne.exe?
Would appreciate some guidance!
Thanks
