Today I updated my nuvi 2508, which had the 2015.20 map on a sd card. Express stated I didn't have enough room on the card, but changed its mind when I manually removed the previous map files. Surely Express should be calculating space without the old map file and removing it automatically?
You are absolutely correct, of course, it does normally calculate the space requirements and delete the previous image that was installed during a map update. Do you happen to remember the exact name of the image that was on the card before you deleted it? Hopefully this is just a one-off but if it happens again we could always take a look at the logs.
Yep, this time it all worked except for the need to manually delete the map files. It's certainly installed them as gmapprom so guess it automatically just deletes files with that file name, I had hoped it was a bit more 'intelligent' :)
In the xml example, your still in the DATA TYPE section. Go farther down in to the UPDATE FILE section and look for the gmapprom element. This has the map region part number, versions (2011), the folder where it is installed, and the file name. If you change the file name then Express will not over write it forcing the prompt for an SD card. If the map is installed on an SD card then there is an Extension in the DATA TYPE section for the gmapprom that defines its path or folder to be installed in. Ex: <Extensions><dtlx:DataTypeLocationExtension><dtlx:ExternalPath>Garmin/</dtlx:ExternalPath></dtlx:DataTypeLocationExtension> Notice the ExternalPath tag. The forums keep making the D a big smiley face. Can't stop it. :mad:
