I have a garmin 650, I have loaded POI files on both my unit as well as my standard SD card. I noticed when accessing files off my SD card it take a few seconds longer to load then files loaded directly on my unit. My question to the group has anyone used the high speed SD card and does it make a difference compared to a standard SD card?
I have i dont see much if any difference!
I have a 360 and have a hcsd card 4gig for my mp3. Anyway I'm using around 500mb and it takes awhile to load everything up. I guess if using any sd card it will take longer to load, also on the amount of data to load.
For the most part Garmin devices are not going to work with a SD HS, ultra or ultra II cards. Just FYI
I use 4gb SDHC in my 660 and also use just a regular 256k first and I don't notice any difference in loading/
It's possible that some of the Garmin's may not be able to use the faster speed SD cards, but my 660 is playing mp3s off from a 2gig. Sandisk Ultra III card as I'm typing this response. I was more concerned with the maximum size it would recognize than the speed of the SD card. Technology is great isn't.
I have a 680 and use the 2GB Ultra II card in my unit and have no problem. I have loaded POI's to it at first, with no problems. I currently don't put POI's on my card since it ran slower than using memory. After deleting files like languages, help files and so forth and loading 200,000 POI's in memory, I still have 750MB memory left.
A a 2gb memory card will be slower than a 1gb card because of the amount of information the processor must run. Therefore, I would use a 1gb card if you want the info to run or come on faster on your unit.
I have garmin 680 and I am currently using a 8gb high speed card to store and play my MP3 files from and they play fine. However, all of my POI files are on the internal storage.
