Thanks for the info. I installed the bluetooth and firmware updates this afternoon and also bought a map update for North America (original maps were from 2010). This is where I ran into a problem - in order to get the updates to fit on the 4gb sd card that came with the radio, I had to delete the western half of the US along with Canada. After researching a bit, it appears that swapping the 4gb card out for a bigger one isn't an option - you are stuck with the card that came with the unit. Frustrating...
