Question about Garmin NUVI 710 Car GPS Receiver
Garmin tech support said it was a problem with new WAAS signals that causes the freeze/black line. Disabling WAAS using menu/system solved it for now. They are working on a software update Real Soon Now.
I read an article in the GoodOldBoat newsletter about the Department of Defense
making changes to the WAAS satellites that have caused problems in Garmin 72
and 76. Garmin's tech support recommended to turn the WAAS function off on
affected units. So I got out my old 162 and turned the WAAS off and it works
fine. To make sure it wasn't a fluke, I turned it off and on several times,
and it always slowed down with WAAS turned on. With it turned off, the
position error or accuracy, increases 1-2ft, not a big deal. I hooked the unit
up on my truck and drove around. Not a problem. Further reading indicates
that other brands of GPS are also having problems with the new WAAS
So if you are having problems with your GPS and it is new enough to have WAAS,
try to turn it off
