zryder-
Have been playing with the
LT-20 and have had simular problems, here are a few things to try first.
Install all of the patches and update files.

Pay close attention to the Article ID DEL00504 and Article ID DEL00573, after doing these updates things started acting better. If after doing this nothing helps....
What I with the help of a friend found out though after playing with this LT-20 is the Lilliput monitor was causing issues (noise) in my truck. To test if you have same issue just boot up everything(after applying all patches/updates) start GPS, try to aquire signal then turn off your monitor, LED on LT-20 turns green? then you have same problem.
Did call Delorme tech support but no help there either, I will be sending back LT-20
to get a roof mounted unit.
Good Luck!
