I am very sorry to come back again, but the utility that I am looking for is the one that allows to enable WAAS.
In your post before last, you referred me to the file vista_32bit_gps_info_utility.zip which is a Windows version.
I am looking for a OSX version of the same file.
The file mac_gps_utility_v2.zip in your last post, which I already had installed, does not allow to enable WAAS.
I need the Mac OSX version of vista_32bit_gps_info_utility.zip
Thanks again for your time.
