I noticed trucking that the display shows the Site ID (which I really like this feature) and System ID,
however when in custom search mode I don't see the Site ID on the display but do see the System ID. Is there a setting to show the Site ID when in custom search?
Yes. I have it set up on my 200.
Go into menu-display options.
Turn the large knob to highlight the area you want to site id to display and then hit E Yes
Brings this up
Rotate the large knob to scroll thru your available choices. When Site id is selected, hit Y Yes on keypad.
After you press E Yes, this screen will pop up again. Hit Avoid on keypad and it takes you back to where you were before you hit Menu...
(note, your only allowed certain items in certain spots. Site id will be accepted where mine is, the 2 slots above, and the 3 to the left. There may be other spots also.)
