Hi,
ComputerTeddy provides a gmapsupp file for the whole earth in 4 parts (planet_neu_gmapsupp1.img.gz etc. on http://wiki.openstreetmap.org/wiki/User:Computerteddy)). How should these parts be combined on a Windows PC into a single gmapsupp.img file for immediate downloading to a Garmin Dakota device?
I concatenated the 4 .gz files to a single .gz file using command line copy and then used winzip to extract the concatenated .gz, but winzip hangs without error message.
Thanks in advance!
Rudy
