Thread: Incorrect time on nüvi 255W

Recently I bought a few old Garmin devices from a "second hand items" shop. One nüvi 255W and two nüvi's 250W. I have updated all through WebUpdater (first) and then GarminExpress. After that, no further updates available for these units. Peculiar thing however, is that the nüvi 255W shows the local time 1 hour behind the actual time. See screenshot below. Both nüvi's 250W show the correct time.

- I checked the units for presence of the gmaptz.img file. All have the latest version (v22.00) stored in the X:\Garmin folder.
- I reinstalled the latest FW again. No luck.
- I took the unit for a drive around (thinking I must use it above a certain speed first). No luck.
- Time setting is set to "Automatic".
- The unit has 5 green bars of satellite reception, so it knows where it is. In terms of navigating the roads, the unit works fine.

Further details below:
nüvi 255W, FW 7.80, HWID 1091
nüvi 250W, FW 4.10, HWID 0737
nüvi 250W, FW 4.10, HWID 0835

Anyone have any ideas as to what I may have overlooked? Thanks in advance!


PS: Forgot to mention:
- Restored unit to factory settings few times. No luck.
