I searched but could not find a thread, so apologies if this has already been discussed. Lately, my kids and I have noticed that when I navigate to a destination, there is a "snail trail," their words, from where we've come, but no blue line to where we are headed. And sometimes there's an empty patch in the middle if there is a nav trail. I thought maybe the connection was just slow, but everything else seems to work fine. And it never catches up. I also haven't been seeing traffic colors indicated lately, and yes, the traffic info is highlighted to on. This is in the main 17" screen. The smaller one in the IC still shows the segments fine. Any thoughts appreciated.
