Anyone else experiencing this? A few times since 6.2 I have had no maps or Slacker. Culprit appears to be 3G connection is lost. I don't receive any errors, but the 3G icon looks like the wifi icon and I check and am not connected to any wifi source. Reboot of 17" screen fixes it. I have reported to the Service Center, but thought I would check in with the rest of you.
