The new credits system is too cumbersome, IMO. It seems great for a new purchaser but it's confusing for a legacy customer.
My cable currently has 2000 F-Body, 2005 Silverado, and 2004 GTO. I would like to have the 1-bar SD upgrade and black box logging for the 2000 F-body and 2004 GTO.
Previously, you purchased a model/year but not it appears it's locked to VINs? I don't want to buy software for all GenIII vehicles. I just want the upgrades for the software I already bought. Is this possible?
