Hi Piotr,

I need it for Porky Piwis, The KTS needs the firmware flashing over to Porsche I have a KTS540 and was just going to flash that as and when I needed to but you can't do it on the BT wireless KTS, I am not sure if the 530 is ok or not, I know it is the wired version of the 540 but not sure beyond that - I shall do some research

Thanks for the offer I'll be in touch

Rob
