GPS not Working on eS127 and eS128 today

[JohnBRI]

Chuck, I left you a PM explaining that I have had major problems with GPS again. Even the RA130 can't get a fix at times. I can't even manual select and change from RA130 to Internal or back with repeated success. If unit powers on with Fix then most of the time it keeps the fix but not 100%. If it powers up with no Fix it is impossible to get a fix no matter what I do. I have attached an error message that comes up 95% of the time when I try a data source command. The 3 pictures were taken in sequence after each try yet I get different results. Internal not there then there. Also took picture in diagnostic mode. Not showing my AIS650 or my 260 VHF which was not powered up but the AIS was. I saw another answer to a question you responded to regarding this error message and got me thinking that I am right. There might be a firmware issue. Please help!
