Hi Everyone,

be gental; newbie warning!!!

I have a 550 and will be going walking in austria soon and I'm trying to get the transalpine set working on my new unit.

I have copied down the UNLOCKED img file, unrar'ed it and copied it to the \garmin folder on my SD card. Its the only one named gmapsupp.img

The unlocked img file come back with a "can't unlock maps" error while starting the 550 and the new file can't be seen under the map manager option on the 550's settings screen. The previous img worked fine on this card, in this folder,with this file name.

Could someone please tell which really stupid thing I've done wrong?

Thanks !!!

Sean.
