I am not really sure where to post this, but Craig Bergh at Midwest Speed Quest contacted me to stay he has some GT-31's if anyone is interested.

Kato Has checked and came up with this reply.
Note, these are in the USA

Has it arrived?

Yep

Um,...... put it in the GT-31 and see if it works????

If it is 2 gig it should work. They changed something about the operation system of the larger cards which made them incompatible with many older devices.

OTOH, I did find one 4GB SD card that runs the older system and is advertised as compatible and works OK, but I think it is a bit of a Unicorn.

Thanks yoyo and Te Hau

Dezza,
I have some spare cards I bought recently, I can give you one next week at Myall lakes.

Just in case anyone else is looking for a new 2gb card for the BT31's, the ebay seller in Melbourne sent me another one which works, pretec 2gb sd memory card, available from www.softdup.com.au
