How I Survived My Zumo 450 GPS
The Battle of the Zumo 450 was hard fought… and won!
I am posting this in case there are other new Mac/Zumo 450 users who may have run into the same issue and didn’t know what to do.
- Garmin Zumo 450
The download process from SpotItOut.com didn’t error, per se. It didn’t actually do anything, it just halted with no messaging. I was on my own to try to figure out why.
I poked around the Zumo’s folders and found that there just wasn’t enough free space to download the 52MB file. I tried several things, including downloading the POI set to a different GPS device, putting the files on an SD card and trying to read it from there. (Which also did not work.)
Does Anyone Know?
Do POI files from Spot It Out get flagged for use with a device ID or something? Why would it not read from the SD card if it was downloaded from another device?
Fed up, I sent an email to Spot it Out.
The instructions I received from Spot It Out were:
You could do the following:
– insert an SD or microSD card into the unit
– connect the unit to the PC, temporarily remove the map database from the device (a file sometimes called gmapprom.img – or a very large file, about 1GB), download our title, then move our title from the /garmin/POI directory to an SD card, then write the database file back to the unit, the unplug the unit and restart. The title will now be read directly from the SD card.
Which I did and… it didn’t work.
Even after dumping that HUGE .img file off of the Zumo there was no additional free space. How is that f’n possible? The answer could only be one thing. Deleting the file didn’t really delete the file.
The following day, Kenny gem that he is figured he would “fix” things for me. Using his Windows laptop, he plugged in the Zumo and started looking through the directories.
What he found was that there is a folder on the Zumo that was not visible when I was looking at the GPS in OSX Finder called: “.trashed”. In it was over 1GB of data.
When I moved the .img file to my desktop based on the instructions from Spot, I copied and pasted the file instead of cutting and pasting. I then deleted the .img file from the Garmin folder. The Zumo put the .img file into its (unknown to me) “.trashed” folder.
Once the .trashed folder was cleared on the Zumo, the POIs downloaded without issue from the Spot It Out site. The newly downloaded POIs were moved off of the Zumo and onto an SD card. Then I moved the .img file back on to the Zumo, unplugged it, restarted it and prayed.
In the Extras on the GPS was the sweetest sight in the whole world – My Roadside America POIs being read from the SD card.
