I uninstalled the previous version and then I saw the package on the Apllication Manager list. I installed the maemo-mapper successfuly. since I have charging problem with my GPS module, I'll let you know if I succeded to download the maps also.
Thanks.
I tried to add the first URL format in maps->manage repositories, but I got an error.
I checked the documents folder and there is Maps folder - how do I use it? are this maps?
