nuvi650 - 4GB SDHC Card
What is the best way to add files to the SD Card for MP3s and custom POIs in order to fully maximize the card's capacity.
What is the best directory structure?
ex: all mp3's in 1 directory - or sub-directories etc
ex: all POIs in 1 directory or sub-directories as well
Also, some say leave POIs on card, others say transfer to GPS memory - which is best to avoid issues down the road.
I put the MP3s and POIs in subfolders. Can't remember about the MP3s, but there is a one level restriction on POIs and subfolders. In other words, you can only have one level of subfolders...example
Just don't put the MP3s in the root directory. Create a folder for them.
I have taken out the manual, extra vehicles, extra voices, etc from my Nuvi (backed them up to my PC). I then have placed my POI's in the Nuvi's memory. Seems to be quicker access. Memory is quicker than a hard-drive. There is plenty of room in memory if you delete the above. I have over 200,000 poi's with no problem. My POI's on my PC look like this:
POI <--main directory
Gas <-- subdirectory
Restaurants <-- subdirectory
As for the SD card, I place both music and pictures in it. I created a main directory for Music and a main directory for Pictures. All music and pictures are then placed into those directories. It wouldn't make sense to place music in separate sub-directories since the GPS doesn't have structure for playing certain Genre or other things like maybe MusicMatch Jukebox on your PC.
