It has a Sansa connection in the dock, but the back has a USB mini-B so you can use a standard camera cable.
While it doesn’t have a charger, it does have a line out.
Hook this up to a USB power plug (you need this for audio from dock to speakers) and line out cable to your stereo and you have a very nice setup for very little money.
I bought one each for my work office, home office, home stereo and for my kitchen radio (it has audio in).
I’m even thinking about how I might use in my car.
