So like a good scout I went to their website and was vexed. That is the most impossible web site I have ever seen. That having been said I called their service number and after listening to a pleasant sounding woman on a recording and holding for about five minutes got a live person. things got better very quickly after that. I told him what unit I had and that at random times the screen would go blank except for a vertical blue line and a total loss of key function. He told me what the problem was. The soft ware gets into an endless loop when getting a fix. He said that disabling the WAAS function would degrade the accuracy some but would allow me to avoid removing the batteries and restarting the thing. I can't tell at this point how much I have lost in accuracy. But my waypoint for home seems to be just as good or bad as it has been.
