I use a TOM TOM GPS, and they have an online Homepage that you can download any updates. I would imagine yours is the same. Look up the Rand TND520 homepage on the internet and look for a PC setup program. With the Tom Tom, I have to connect it to the PC with a USB cable and it automatically downloads and updates itself.
