Chamuni, I to purchased nuvi 550, my first gps and very satisfied with my choice. I after going through the online registration process couple weeks later recieved a email informing me of a update. After installing the update the download also installed the most recent Mapsource program onto my PC.
Looking into the tools>settings>Map and at the bottom bar is map info there I found what maps I have on the unit. whether it's SD card or installed.
I hope this helped
