Sorry if this has already been posted, but I have not seen it posted here.
I just found where you can enter a custom start up message on the 62 series.
On my 60, I entered name and phone number, that showed up on start up.
In order to duplicate that on the 62, you need to hook up the USB, navigate to
<drive>:\Garmin
and edit the startup.txt file.
Here's the contents:
<!-- Edit this file to display a message while your unit is powering on -->
<!-- Allow one full power cycle after editing for your message to be updated -->
<!-- Set the display number to the minimum number of seconds your message is displayed -->
<display = 0>
<!-- Type your message on the next line -->
So after that last line, whatever you enter pops up on the start up screen.
Works great!
