    Default Moving SD card from Etrex 20 to Etrex 20x - Can't Authentcate Maps

    Hello,

    I've just purchased a Etrex 20x to replace a worn Etrex 20.

    I cannot see any of my 1:25000 UK maps Garmin GB TOPO PRO maps on the maps list and I get the Can't Authentcate Maps message when i start the unit.

    I've done an hour long sweep on this forum and others and I cant work out whats up. the only fault in JaVaWa is "Error: segment codes from this file reside in other files. This will cause problems with routing and/or displaying maps."

    Any help would be greatly appreciated.

    Thanks

    Alex

    Thanks Butters - I did see this I was rather hoping to do it without such means - I'll have a look into it however these are devices for work thus if the risk too high I'll leave it alone.

    Thanks again,

    That was the wrong link I'm sorry, I didn't check properly. Your etrex isn't a protected device and you only need to unlock the map img files with gimgunlock. The thread has been removed but you can get get a download from this link:

    Usage: Simply drag the locked *.img file onto gimgunlock.exe and wait for a few seconds and the map will be unlocked for use in other 'unprotected' devices. Make a backup of the original map img file before you start.

    Actually, even the very first version of gimunlock will work for his etrex because it has "MVS: ---" and "GSV: ---". Certainly latest will work for sure as well as original though for an etrex.
