An update on the navman drama. For the reader's digest explanation on how to work around the daylight savings problem, scroll to the bottom.Otherwise, read on for the full saga...
Jason's response referred to an internal spreadsheet. When things were zooming around in my head while thinking about something totally unrelated (as happens for all of us), I remembered that you can hook up a Navman to a PC via the USB cable and access its data, the PC seeing it as another drive on the PC. So I plugged in, and found the file. You can download it here. The file on my 'downloads' section linked to is the unadulterated file as provided on your Navman. You'll find it on your Navman at <navman drive letter>:\Program Files\Navman\SmartST_CE\Data I located the row that is relevent to me:
| ID | STD ABBR
| STD NAME
| DST ABBR
| DST NAME
| GMToffset | DST Adjustment
| DST Start Date Rule
| Start Time
| DST End Date Rule
| End Time
| | Australia/Sydney | EST | EST | EST | EST | +10:00:00 | +01:00:00 | -1;0;10 | +02:00:00 | -1;0;3 | +03:00:00 |
Now, does anyone know what "-1,0,10" means? One presumes that the 10 refers to the month to commence daylight savings, just as the '3' in "-1,0,3" is assumed to refer to March in the DST ending entry. So, what does "-1,0" mean? I assume that the '0' means Sunday, as in the change occurs on the first day of the week. But what is "-1"??? Anyone? Help? *** 15 minutes later *** Ok, I gave up... I manually edited the timezone to be +11:00:00. There's a trap for young players here: you can't use Excel to edit the CSV, because it sees +11:00:00 as an attempt at a formula once you edit the cel: so open it with Notepad. CSV files are, after all, comma-separated text files. But the device can't see the sattelites... so I've reset the GPS in the options menu. Watch this space... *** 5 minutes later *** The hack worked. I just need to change it when it thinks daylight saving is to begin! In Summary:- Plug your Navman S-series into your computer using the USB cable.
- When the PC asks you how to handle the USB device, select "View files and directories" or whatever the equivalent is on your platform.
- Navigate to <navman drive letter>:\Program Files\Navman\SmartST_CE\Data
- Locate the file Date_Time_ZoneSpec.csv
- Copy it--you can keep the copy on your Navman!
- Edit it with Notepad/Word or some kind of text editor. Don't double click it because it will open with Excel or whatever spreadsheet you use. That presents the data in a prettier, but uneditable format.
- Find your time zone (e.g search for "Sydney").
- Alter the time zone... for example, Sydney's standard time is +10:00:00--so you edit your Navman to read +11:00:00.
- Save the file (as a CSV--so if you're using Word etc to edit, you'll deliberately to save it as a TEXT format, CSV extension).
- You shouldn't have to "RESET GPS" but if you do (as I felt the need to), go Main Menu 2/2, Preferences 2/3, GPS Status, and hit "Reset GPS".
QED.
