I have downloaded europe 2011.10a unlocked and expanded all the files into one folder. Is just a case of deleting the old map in the device and insert the new.
Are there any instructions anywhere forthis proceedure or what to do with these rar files.
thanks
I'm not exactly sure what you downloaded. If you downlaoded and unlocked img of all of Europe, all of those RAR files should have been automatically extracted into your folder and produced about a 1.6 to 1.9gig file named either gmapprom.img or gmapsupp.img (these are your new maps and all you need)
What other files were in the archive ? Also, once you have unpacked that archive you have no further need for the RAR files unless you want to save a copy of the download in a smalleer size.
If you have the large unlocked .img file, that's all you need for a 760. Other files are for models that support features you don't have.
Your 760 pre-installed maps are in the garmin folder and are named gmapprom.img
You want to replace that file with the new unlocked img file and your done. The new one should be named gmapprom.img in the 760 although either name will work.
You may want to first copy your original gmapprom.img to a PC as a backup strategy.
Your looking at a 3-4 hours worth of time to transfer the old file and load the new. Transfere from/to the 760 is s-l-o-w over usb.
