Hi Everyone,

be gental; newbie warning!!!

I have a brand new Oregon 550 and will be going walking in austria very soon and I'm trying to get the transalpine V2 set working on my new unit. Ijust can't spend £180 for 5 days map usage.

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

The garmin comes 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.
