On our latest trip that started at the end of June I started experiencing a strange problem with my 660. I'm using a PC with Win 7, BC 4.2.2 and NT 2013.4 maps on both laptop and 660. After plotting my routes in BC, transferring them to the 660 and checking them when I start a route all works as it should then somewhere down the road the distance to next turn disappears and the top line displays "Arrive Continue" or some times it's blank. The map still works but the announcement of the next turn is abbreviated and doesn't make any since. Turning off the unit or stopping and starting the route doesn't solve the problem. The only thing that seems to work is to recalculate the route and even then some times the problem comes back. I contacted Garmin tech support but the tech was absolutely no help.
I've noticed a discussion on this problem on another forum but with no resolution. Any help would be greatly appreciated as this is driving me nuts.
Oh, I forgot to mention, my 660 is using the latest firmware (not sure what that is)...
