Looking at picking up a 660lm when a good sale pops up. It says it has an onboard mp3 player. Does than mean that I can plug in a sd card or do you have to load the music onto the unit????
I think what folks are saying is you can load music on the SD micro card and play them on the gps. But there are conditions to be met, at least on my older nuvi. Check your manual.
- music format matters. It must be in mp3 (and maybe mp4) format. The nuvi will not play anything associated with Windows.
- the music isn't just put on the card. I had to create a folder named 'music' and put the files there so the nuvi could find them.
- I'm limited to about 800 songs on the card. Any more and the nuvi just locks up.
- Staples, WalMart, Office Depot, etc all have SD-to-micro adapters. Just buy a micro that comes with one. Transferring files is transferring files, you know how, yes?
Again YMMV but .....
