I’m living at the corner of 3 map areas, to get all the data I want for cycling (looking to transfer maps onto new Garmin 520) I have to download 3 areas together, giving a total file size of 46Mb. The Garmin has only 50Mb memory.
Is there any way I can reduce the size or area of the maps to give a smaller file size and so my location is centred on the area I need?
This gives me one map that covers the whole of northern Europe and is 88Mb in size. I can’t fit that on the Garmin. Can these maps be scaled down to give a smaller area?
I’m looking for a detailed map that covers Yorkshire/Derbyshire area and will not take up too much space.
I clicked the Mac OS X install and it gives me a command line prompt which is a bit too technical for me to sort. I’m looking for a map of west yorkshire + derbyshire region that is no more than about 20mb in size. Can you help guide me through what I have to do with the big NW europe map to trim it down to the tiles I need, that I can fit onto the new Garmin?
Thanks! This looks pretty great for selecting the right area. I’m guessing Garmin cycle format best to use, if I can get it to transfer over to the Edge 520 (when it arrives…)
This is very user-friendly for selecting and downloading an area as a gpsupp.img, but I cannot then install the img into Basecamp. I’ve spent hours trawling through google searches and gps/mapping tools but there doesn’t seem to be anything for the mac? I want to be able to preview the image files and install them into basecamp.
I found 2 solutions for the Mac, to check the map areas in Basecamp once downloaded from bbbike. I plugged in the Garmin Edge 500 which although it doesn’t support maps, basecamp recognises it as a legitimate device to read the gmapsupp.img files from - just copy into the device Garmin folder.
I also found omg files in a Garmin folder on SD card worked the same (and was quicker) whereas when I tried it with a USB stick, basecamp would not recognise it as a legitimate device.
