16GB SD card works

Out of curiosity, I bought a 16GB SD card and slapped it in my Zumo 550. At first the unit would not read the card. I reduced the number of songs on the card to below 1,000 and it works just fine.

Note: I had to power down the Zumo and then turn it back on before it would recognized the SD card.

Final note: Garmin states that the Zumo has a 1,000 song Playlist limit. I originally thought that I could have multiple Playlists on a single SD card -- with no more than 1,000 songs in each Playlist. In fact, what Garmin should have said is that the Zumo has a 1,000 song Library limit.

NB: Based on what I've found, I'd have to agree with JSTCRASHNTHRU -- there's not much reason to get an SD card bigger than 8 GB because, even at the highest bit rates, 1,000 songs is only going to need ~ 6-8GB.

Very true, unless you also want to add some additional maps (500 models) and/or topo maps, together with your juke box.

(Taking 2 cards with you works just fine as well ;-)

file count

Man, am I an archeologist or what?

Thought I'd throw this in, since this is nearly the first result of you Google the Zumo 550 SD capacity. If you're on a Mac, or have Cygwin on your Windows computers, you can easily count the number of songs you have on an SD card using terminal

- Open
- Put your SD card into your computer
- Type this: 'ls -l /Volumes
- look at the output and find the name you've given your SD card
- Type "find /Volumes/YOUR_SD_CARD_NAME_HERE/music/ -name "*.mp3" | wc -l"

The output will be the count of mp3 files in the 'music' directory of the SD card.

Example from my 4GB SD card has 3.6GB of songs on it, mostly 128hz bitrate, the typical bitrate for ripped or purchased songs). Doing "find /Volumes/5504GB2/music/ -name "*.mp3" | wc -l" will output "648". Given that, I think an 8mb is about the max if you're interest is just having room for music. If you're keeping your stash of Jayme Langford photos on your Zumo , just keep in mind you'll max out the 1000 song limit somewhere around 6-7GB.

For windows it would be something like 'dir /a-d /s /b music | find /c ":" from the command line (once you had used 'cd' to get to the right directory on the SD card). For you Windows users without command line experience, I think using the UI you can get the properties of a folder, and it shows a recursive file count there.
