Just back from Leicester today - around 450 miles with my Zumo - having upgraded from 4.1 to 4.2 on Monday all was well initially but today the unit in the bike mount just kept freezing and would not select the right riding icons - at one point a new splash screen came up asking for me to verify my country... I removed the 16gb card and amazingly upon restarting the 660 was performing as well as before but now I have no music. Has anyone else had this problem, I did not try my 8gb card but dropped Garmin a support email tonight - lets see what they say?
