My unit powers up in the sim mode and I can't get into regular combo mode.
I have been using the unit in my truck running in GPS mode on the optional power cable with the sonar off and on the boat in combo mode with no issues.
In prep for up grading the software, this week, I turned on the unit on the power cord and went to apply default settings. It came up in demo mode. Also, my recent tracks did not down load in HumPC.
In demo, the screen says to press the exit button to leave demo. This has not worked nor has switching off and disconnecting power. This has been going on for 3 days.
Thanks, Mike
