I have a GO 2535TM (App 11.037.920860.84) (0) (3015, 4/5/12), OS 824205 and the time will not sync even though I have a great GPS signal. It is showing Sep 18, 2010 instead of Apr 9, 2012 and the time will change every time I get any kind of update. Is there a way to get this to sync the time and date?
