Ist das ein Thema für den Triton 500?

I am not sure about this problem, but there is the SirfStarIII GPS chip in the Magellan Triton 500. This chip can communicate with Triton hardware and software using NMEA data transfer protocol or Sirf Binary protocol. This device using NMEA for normal working process, where an information from GPS chip to CPU is transmitting as a simple text messages. You can find a list of NMEA messages in the Internet. Here are some of this messages

RMC - NMEA has its own version of essential gps pvt (position, velocity, time) data. It is called RMC, The Recommended Minimum, which will look similar to:

$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A

Where:
RMC Recommended Minimum sentence C
123519 Fix taken at 12:35:19 UTC
A Status A=active or V=Void.
4807.038,N Latitude 48 deg 07.038' N
01131.000,E Longitude 11 deg 31.000' E
022.4 Speed over the ground in knots
084.4 Track angle in degrees True
230394 Date - 23rd of March 1994
003.1,W Magnetic Variation
*6A The checksum data, always begins with *

ZDA - Data and Time

$GPZDA,hhmmss.ss,dd,mm,yyyy,xx,yy*CC
$GPZDA,201530.00,04,07,2002,00,00*60

where:
hhmmss HrMinSec(UTC)
dd,mm,yyyy Day,Month,Year
xx local zone hours -13..13
yy local zone minutes 0..59
*CC checksum

So, there are "day", "month", "year" data fields, but there is no "week" field.

Das gibt Hoffnung

So, let's wait until 6 April

Schon 7 April .... nichts passiert

I think, I was wrong.
This problem was not a joke.
Here is the article about this https://www.energy.gov/oe/articles/apri ... r-rollover
Some users from russian forums reported about the problem with their old Garmin eTrex Legend CX devices (see the picture attached). That device is unable to fix the position, and date on the screen is wrong.

P. S. my Garmin Oregon 300 is working OK.
