Thread: eTrex Touch 25/35 software version summary

Try to "click the "LIKE this post" button and hit F5" and see what happens.
On the other end, I bought an Etrex 30x last week and so far every unlocked map runs on it, even the CN Europa NTU map (although I did not buy it to run CN maps)

Firmware running is v2.0, so I won't be checking for firmware updates, just leave it as is.

I've just done a firmware update to v2.10 on my eTrex 30x and have encountered no problem so far with CN Eur NTU.

Warning:

The update of eTrex 30x to firmware 2.10 may cause authentication failure of maps.

I did an update recently, and the maps that were already on the device worked perfectly.

Just added a new map today, and it failed to authenticate map.

Do not upgrade. Sorry for above misinformation.

The City Navigator maps that were on the device before the update worked after the update.

After the update, putting in City Navigator maps, regardless of regions, would fail authentication. Applying gimgunlock+mapsig won't work. Temporary authentication method won't work either.

I downgraded the firmware back to version 2.00, and all City Navigator maps work fine now. You can check the Garmin firmware section here to get version 2.00 and another earlier version.
