Mekede-mall clearly sent me the wrong canbus box with my HU. They sent me the Simple Soft (XP) GM-SS-05 which only works with the GMLAN 29bit. My 2010 Cobalt is 11bit. They are now telling me "If you want to buy a new CANBUS, there will be a charge. The price is not high, but the shipping cost is very expensive now. It is recommended that you search for relevant CANBUS on Amazon.". That is a bunch of BS! Send me the correct GM-rz-01 like you should have from the beginning!
