You will have no problem to use our data on your device despite that you have Mac with no option to run SmartST software. All what you need is to be able to browse your GPS Navman-iCN 520 device and and to copy files to mypoi directory on your Storage Card. You can use our McDonalds test data for your total confidence. Another option is to use software called Guest PC. It is another computer inside your Mac. That computer is an emulated x86 PC. You can install all Windows based software including Navman SmartST. In that case you just need to follow easy installation instructions from Navman POI data download zone.
I'm anxious to download Advanced for my new Navman 520 and we are exclusively a mac office. Is there anything different or I need to know?
