TTO SD recommendations ?

[Viper]

I've been using a ByteStar 1MB card but its very tempremantal when used in the TT, some times TT recognises other times I get swap card type error, when I have to install the OE SD

what SD card brand works OK ?

I just brought the western maps CD and cant upload to the current 1MB card...
