Download the file you are interested in, unzip it, and save the unzipped file as GMAPSUPP.IMG and then upload it to your Garmin [make sure you have sufficient storage space first] and backup any mapsets you have already installed. If you don’t have a program to handle/unzip ZIP files I would recommend 7Zip which is available FREE from here: http://www.7-zip.org/.
To upload/install one of the map files to your Garmin GPSr, you can either used Sendmap [available from here http://www.cgpsmapper.com/download/sendmap20.zip ] or if you have a later model which uses MicroSD cards you can either load them directly on the card, or by using the direct USB Mass Storage mode found in any of the HCX or equivalent models. In this case just place the GMAPSUPP.IMG in the folder named GARMIN.
Please note: Uploading the GMAPSUPP.IMG to your Garmin GPSr [or MicroSD card] will overwrite any existing mapset you have installed on the device using the same name. This should not effect the basemap that came preinstalled on the GPSr.
If you have any problems installing the map file or are unsure of how to do some of the steps then take a look at the FAQ here. I also offer a service to do this for you on a MicroSD or SD card that you supply, or if you prefer, I can supply a pre-loaded 4GB or 8GB MicroSD or SD card, see point 5 in the FAQ for full details.
Please ensure that you only have ONE of my contours maps (Standard or TT
1:50K) on the internal memory and/or a MicroSD card at a time as
otherwise your Garmin may fail to boot.
Please note: The newer Garmin Nuvi devices may use a directory called MAP rather than GARMIN to store other maps in (such as the ones I offer here).
Please note: Only the newer Garmin devices support cards up to 32GB (they will NOT support 64GB or larger cards). Older Garmin devices will usually support up to 8GB cards (with the latest firmware installed).
I try and compile new versions of these maps between every 1 to 2 weeks, however, I can only do this if I have some spare time as they require a lot of work to download the tiles, sort them out [and split them, in some cases], compile them into the relevant GMAPSUPP.IMG files and then test them to ensure that they are complete and functional on both a computer and my GPSr.
