I never saw any reason to move the map files and waypoints out of the gps' internal memory until it was full. This never happened on my 660 or on my 595. I was also never instructed to do this by Garmin support either?? I assume the internal memory of the unit is faster than the external SD card anyway, so why move it. That would be the equivalent moving the programs on my PC out or RAM and running them from the swap file on my C: drive, or even worse, on an SD card!? <If> the internal memory, which I also assume is were the firmware is stored, never fills, why move these files? I did have this issue on some of my earlier Garmin devices where the maps grew to be larger than the internal memory, but that hasn't happened in years. In that case, yes, I moved the map files to SD storage.Its not the operating software that causes all of the problems, its the map updates that continue to get larger and larger and consume all of the devices limited memory resources. Its not actually the maps getting larger its the POIs. The continue to add new ones but dont clean out the old ones. Off loading the ever increasing map update file to a large sd card did wonders for my 550, which used to crash and freeze before doing that.
It may be a matter of semantics, but, in my mind at least, the Garmin memory isnt really firmware. It works more like a solid state hard drive. When I saw how full that ss hard drive was after a map update it gave me the idea to free up space on it by moving the giant map update file.
Im still using mapsource because basecamp has always sucked. It does crash during route building occasionally, so I do a lot of saves while making routes. The key to using mapsource with later version devices is to not use it to transfer to the device using it. Instead, create your routes and waypoints then save the file as a .gpx file on your PC. Transfer that file with windows file manager to the GPX directory on the device and import the data from there. You can use the same technique from basecamp.
I do store a LARGE quantity of mp3s on my gps SD card. That is an appropriate use of SD storage. The streaming of music won't be effected by the slower SD memory access speeds. I did have locking up issues when I had thousands of mp3s stored in folders which was the result of copying them directly from my home audio system drive. I have over 1TB of music stored in a DIR hierarchy of \band\album\mp3 structure. The Garmin chocked on the DIR structure. After simply dumping the mps3 in a common folder those lockups ceased. I'm figuring these issues were attributed to the length of the path\filenames exceeding a coding limit in the media player.
