Hello,

I was looking to load a Talkytoaster map ( TT50-BRITISH-ISLES+CONTOURS-DEM.IMG ) onto the internal memory of my Etrex20x.

So I have dragged off the Etrex20x internal memory the file GMAPPROM.IMG (file size 3.51gb) thinking this was the file holding the basic garmin maps.

However the Etrex20x has not relinquished the free space I thought would be created by dragging off the GMAPPROM.IMG file... I am told only 300 mb is free on the device...

And as a result now I cannot copy back onto the Extrex20x either the GMAPPROM.IMG or the TT50-BRITISH-ISLES+CONTOURS-DEM.IMG files.

Most annoying... anyone any ideas how to fix this ?

The issue could have been bypassed by the installation of a micro sd card in the Etrex20x with the TT50-BRITISH-ISLES+CONTOURS-DEM.IMG file on the micro sd card...

However I also had problems earlier on today with the Etrex20x not being able to 'see' and load the Talkytoaster .IMG file from my brand new Sandisk 32 gb micro sd card... I suspect the micro sd card was corrupted as I could not format this card on either my mac or pc.

Which is why I have gone down the route of attempting to free space on the Etrex20x itself by dragging off the GMAPPROM.IMG file and lo, now find myself in the mire...

I have ordered a new Sandisk 16 gb micro sd card on which I will place the Talkytoaster .IMG file; and i will attempt this later today.

But... what it going on with the Extrex20x not showing the free space ?

When it rains etc etc... thanks for any tips.
