SD card compatibality

SD cards greater than 4GB's are designated HC. Both will work on nuvi's... HC cards are 4GB to 32GB, Next in line will be SDXC they will supposedly be capable of 2TB... A terabyte for a gps or camera? Amazing..

edit: see http://www.sdcard.org/developers/tech/sdxc

I would stay away from Camera or other specialty cards (some may have special formatting). All others should work.

works fine in my 765T.

be careful about loading it with a ton of mp3's however...there is a limit of 1000 tracks, or the nuvi gets a little confused and you can get some erratic playback.

Panache,

No worries. While some (older?) card readers won't read the SDHC format the Garmin seems to work fine.

I have an 8gb SDHC card here ($12 on Amazon by the way) so, curiosity piqued by your post, I put some music on it and popped it into my Nuvi (760). All songs play fine. Apparently incompatabilities between SD and SDHC are old news or Garmin's engineers have dealt with it.

BTW 8gb = 8000 minutes of music/4 minutes per tune=2000 songs. That should be enough for a road trip.

Oops, edit. I was writing this and playing with the card in the Nuvi so didn't see the previous post indicating a 1000 track limit. Make it a short road trip. You could always use the extra 4gb for pictures, maps or ???

... for the info. Woot had Kingston SD4/8GB 8GB SDHC Class 4 Flash Card for $10.99. I remember problems in the past with a 76CSx and Ultra MicroSD cards. I should have gotten at least 1.

that 1000 track limit was posted here by someone, Motorcycle Mama I believe, and I confirmed that it applied to my 765T via an email to Garmin.

the erratic behavior I was referring to involved creating a playlist with about 1300 tracks (before I knew about the limit), and using the shuffle option on the nuvi.

perhaps just playing tracks in order, or larger/longer files such as audiobooks and podcasts, may not have resulted in that behavior.

but I am going to stay under 1000 tracks from now on just to be safe.

and because I bring my 765T in from the car when I get to work each day, I have used the extra space on the SDHC card to transfer spreadsheets and word documents home to work on, since when connected to a PC, the card has it's own drive letter so I can drag and drop files of any type, not just mp3's.

I have had good luck with AData products and recently bought an 4GB SDHC AData card. When I popped it in the nuvi, it said the card needed to be formatted. I tried formatting it and it failed. I then found an SD USB card adapter, put the card in it and plugged it in the port. The card formatted fine and I was able to put data in it no problem. Then put the card back in the nuvi and it said the card needed to be formatted.

I didn't think I had another SD card around but found a 1 GB in my piano keyboard. Tryed that in the nuvi and it worked fine.

So even though Garmin says any SD card of any capacity should work in their units, that doesn't seem to be the case.

I am using a 16GB sd card in my NUVI 760. It would not accept such a large card until I updated to the 4.6 software.

The drawback to using a large card, is that bootup, particularly drawing the map is slowed down. It will sometimes take 2 to 3 minuted, after satellite acquisition, to draw the map.

I checked with Garmin software people and they verified that a large SD card will indeed slow down the process.

Also loading a large number of music files directly from my computer, to the GPS is an extremely slow process. I therefore copy them on to the card using a high speed reader/writer ( speeding it up by maybe 10 to 1), then insert the card into the GPS. Works great..

when I bought my 8GB Transcend SDHC, I found that it wouldn't work with my older USB flash drive style card reader, and so I picked up a new one that supports the larger capacity for 5 bucks.

now that I am aware of the 1000 track limit, I want to reload the card, and I will try your tip of loading the card outside the 765T with the adapter, and see if I notice the speed difference.
