Hi could someone please remind me which sd cards you can use in a GT 31?

I broke the old one - stuck in lock mode

Thanks, Tom

I find these ok ebay

I bought these no name cards on ebay and work perfectly. $10 AUS for 2 inc postage.

+1 ^

The big factor is that they can't be larger than 2GB. Larger ones are slightly different and don't work. 2GB with take many years to fill up anyhow. I am using a couple of 512MB and 1GB cards and I think they still have the original sessions on them from when I first got them 10 years ago!

a micro SD card in an adapter will also work, the 2gb rule still applies, and sandisk is one of the makers that works.

thanks for the help fellas
