I originally had a the older serial port interface but a few years ago upgraded to the newer USB cable interface. My cable says I have -4 gm credits now...wtf? I want to add a friends car to the cable for the 2 credits it should cost but I want to know if this "-4" means i will have to purchase 6 credits to get him added or will i be able to just purchase 2 like I want?
