I just bought GT2.1 EX. (For my 1/12)

1. Do I need to upgrade the software to run the 1s?
(beeps and flashes green now when I plug in 1s)

2. Is it with a USB cable, or do I need something more (like a spoken LEDbox??)
(incase; where the heck can I buy this usb cable?)

Have search the whole internet for an answer of the first quiz, without any results. And the manual doesnt tell me either...
