I had recently bought a GM Tech2 to help troubleshoot and diagnose issues that may arise on the my 07 GXP. My radio started giving issues, so I picked up a new UUI one from a junkyard online. I was able to do a VIN relearn with the Tech2, but the volume and chimes were too loud. The radio was supposed to have come from an upgraded speaker RPO, but apparently it didn't. From my research it seems I can buy a subscription to TIS2Web and apply the correct programing to the radio to get it to interact with my monsoon system and have normal volumes. This is were I am confused and have concern. Apparently GM/ACDelco have changed their subscription models. I see: "Vehicle Programming Software Includes: 24 months access to program all modules for one vehicle (VIN)" and Tech2Win 3 day and GDS Light duty 3 day. When I called they said I would only need the Vehicle programming software piece. However, to program this radio, since it wasn't an option on my vehicle on my car until 09 and it came from another model, I need to "trick" TIS2Web and use the VIN from the new model to be able to see that programming and apply it to my vehicle. Can I do this with the one VIN programming subscription? It seems for the price difference the 3 day options give you unlimited, but which one would I use? I know this forum might not be the best place to answer this question. I've already scoured the web and looked at other car forums and even called, but their answer wasn't warm and fuzzy clear. Any help to point me in the right direction is appreciated.
