Maps for Garmin Etrex Vista HCx

Your best bet is to pony up for the City Navigator Europe. If you buy direct from Garmin they're about £80 for the DVD. the mapping isn't wonderful - but still, decent street maps for the whole of Europe for £80 is a bargain. The version on memory card is even cheaper but you can't use it on the PC and it means you can't use the card slot for anything else.

I would agree that the garmin Europe maps on CD are the best bet - maps are not OS standard - but are pretty much spot on - detail varies from country to country - and in conubations ie Paris can be too much - certain countries up to and including cycle paths although it is difficult to tell before you get there - you can keep the download to the garmin small by just picking the area you need - also is updated by garmin fairly regularly

Dead easy - download the programme to your computor - run the updates - select the maps you want and hit the send to GPS button

I did hoek of H to Stavanger last year and downloaded the maps I needed plus quite a bit more in about 20minutes - I have a 1Gb mini SD in the garmin

I am thinking about a very long trip and have not got around to doing the same for it - I suspect the whole lot will go onto one card plus space - maps are vector rather than bitmaps so use less space - when I get around to it I will post again

It was a very long download more like 8hrs but it seems to be succesful - now to do the same for GB

[/quote]Word of warning. When you load new map sections into your garmin, it overwrites what is already there. Not sure if this is the way I did it or standard.

No it seems that this it what it does - only allowed one map folder?

Garmin Etrex & 60C(S)x models that use SD cards take their mapping data from a single file called gmapsupp.img, in the garmin folder. Mapsource merges separate .img tiles, which may come from different products (eg Topo, City Nav) into the single gmapsupp.img file before transfer onto the card.
You can have separate map sets on the card, but only the one that's currently called gmapsupp.img can be used. There is no way to rename the files on the GPS, but you can rename them some other way - eg when connected in USB mode, or by taking the card out and using some other device that can both take the card and rename files (eg a suitable mobile phone).

If anyone has a newer GPS (605/705 or Colorado/Oregon), let us know whether the same applies.


City Nav Europe v8 has 212 tiles
TopoGB v2 has 752 tiles (ish - some appear to be all sea)
The limit in a single gmapsupp.img file is 2025 tiles (iirc), but I think there's also a file size limit of about 2GB.
I believe that Metroguide tiles are much smaller than CN, and it's when using this that the limit on tiles comes into play.
