I just purchased the Nuvi 765T and an SDHC 4GB chip. I connect the Nuvi to the computer and the computer recognizes the Nuvi and shows the SDHC, but as a separate, "removable" drive on the computer. I've copied files onto the SDHC chip, but I can't locate them on the Nuvi. What am I doing wrong or how do I make the Nuvi recognize the SDHC chip? Thanks.
getting SD card to allow garmin to see map on it Posted: Thu Mar 04, 2010 04:06
You must create a directory on the SD card and name it garmin. ALL files go into that subdirectory or, yet another sub-directory beneath it (such as more poi files).
The map you want to put on the SD Card must be named gmapsupp.img and it must be either already unlocked, or have the gmapsupp.unl file present for the map to work. You can have only one gmapsupp.img file at a time although you can have many (map or other) files there and rename everything when you want to change one map to active state.

I have a Garmin Nuvi 765T and have installed a Sandisk 8GB Pro Duo SD card but cannot see this as a drive on my computer? Has anyone had this problem or know if this card is not compatable with a Nuvi 7 serires?
Garmin Navi 765 SD storage card Posted: Sun Mar 07, 2010 11:39
I also have a Garmin Navi 765T and use a 4 gig SD card for media. Mostly MP3 music files and 4 Gig holds quite a lot. I have a Sandisk and a Kodak whiuch I swap for a different library. That works great for me.
Have not tried to store maps on the SD card though and with 4 Gig on board the Navi, why would you?
A great unit and very happy with the support from Garmin.
