Onboard memory?

 I purchased a Woot special SanDisk Sansa C240. This model is supposed to be a Refurb 1GB v1. The memory slot is empty. Does it have 1GB of memory already onboard or do I have to purchase a 1GB or 2GB memory stick to install. Thank you!

It’s got 943 MB available on-board. I think the micro SD slot can handle another 2GB.

Thanks muchly!

i can’t use entirely my c250 2GB memory.i only can used about 5++MB only…what happenned?can someone in here help me find the solution?

Try to format the c250 in MSC mode through Disk Management.
