#Using garmin mapinstall download

In my case the 'Error' was due to Express being unable to find suitable free memory on the GPS unit (a Nuvi56 satnav) with 8GB internal memory and an 8GB microSD card, it had the previously installed City Navigator Europe map=2.4GB, and 2 third party maps, (OSM=700MB and Toasty Talker=2.3GB), all of which were on the internal 8GB leaving only a few hundred MB free, the problem was that although there was an almost empty 8GB microSD with only 140MB world maps on it, the new map which was 4.8GB was not sent due to Garmin MapInstall only 'seeing' the microSD as 4GB not 8GB

#Using garmin mapinstall download

I have recently had problems when updating the Lifetime maps from Garmin using Garmin Express, the download fails with an 'Error' message, there are 3 options when performing a map download using Express, they are 'To GPS unit only', 'To computer only' and 'To both GPS unit and computer', I used to select this last one so that I could use the map with Garmin Basecamp even when the GPS wasn't connected to the computer, however If you are getting download failures I would select 'To computer only', This will allow you to see the new map in Garmin Basecamp and then use Basecamp to send the map (or part of it) to your GPS.
