Garmin Nüvi 50 with OpenStreetMap

Posted by Skippern on 9 July 2013 in English (English)

My wife have recently been on a holiday in Europe, and one of the things she brought back was a Garmin Nüvi 50 Car Navigation System (with preinstalled maps of western Europe with speed camera information). Western Europe map is close to useless for me, so I quickly dived into the fountain of wisdom called the OpenStreetMap wiki, as well with other GPS and Garmin sources

After trying a bit different sources, copying maps in different formats to different places on my GPS I found the following to work:

  • Go to Garmin Dashboard WebResource
  • Install the plugin they suggest
  • Go to garmin.openstreetmap.nl
  • Select the map regions of your interest, along with stylesheet, etc, and generate
  • Download the gmapsupp.img file, zipped
  • Unpack it to Garmin Device root.System\ folder
  • Replace your gmapsupp.img over the existing gmapprom.img

I liked the interface of garmin.openstreetmap.nl, the only thing that wasn't completely clear to me was source age (are they generated from minutely updates? daily updates? weekly updates?

I am now just looking for an opertunity to take my GPS for a spin to see how good the maps are. AND: When I see something wrong on the GPS, I can take up my iPhone or iPad and correct it on the fly with Go Map!!, that way next time I download a map, it's already corrected.

Next step will be to find out how I get POI displayed in a zane way on my Garmin Nüvi 50 device

Location: Centro, Guarapari, Microrregião Guarapari, Greater Vitória, Mesorregião Central Espírito-Santense, ES, Brazil

Hi

'I liked the interface of garmin.openstreetmap.nl, the only thing that wasn't completely clear to me was source age (are they generated from minutely updates? daily updates? weekly updates?"

You can see the age of the data directly beneath the slippymap on garmin.openstreetmap.nl.

The text is ....

Hosting is sponsored by Oxilion and others. Slippy map and Garmin maps are based on OpenStreetMap data. Map version: 07-07-2013

the Map Version shows the date - i.e. 7 July 2013

In http://forum.openstreetmap.org/viewtopic.php?id=2625&p=1 Lambertus wrote "I'm aiming for worldwide coverage on http://garmin.openstreetmap.nl and hope to update these each week". In my experience you can expect an update once a month.

Thanks for the feedback

I have experienced a few "bugs" in the map, and already corrected some. A few new POIs have been added and of course a few more streets. I'll aim to update my map from time to time - and keep looking for routing mistakes to fix turning restrictions and other details. Next tool would be a mapdust tool for iPhone to make notes where I need to go back in JOSM later to fix
