do you have HPTuners or experience with it? does it make sense to purchase? if i did purchase could you show me the basics with it?
the directscan on the LC2 powered cars is most i have exposed myself to.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The radio theft deterrent system disables functionality if the VIN information received by the radio does not match the vehicle VIN information. The radio receives the vehicle VIN information through GMLAN. If a radio is replaced or swapped from another vehicle the radio will need to relearn the VIN information from the vehicle before it will function. If the VIN information of the vehicle does not match the learned VIN information in the radio, it will display "LOCKED" or "THEFT LOCK".
Recommendation/Instructions:
Currently, performing the radio setup in SI (Document ID # 1745049) will not learn the vehicles VIN information to the new radio. Engineering is aware of this and working on a correction.
A temporary solution is to perform the radio setup in SI (Document ID # 1745049), as well as, perform a VIN relearn. To perform the VIN relearn, build the Tech 2 as follows:
F0: Diagnostics

F6: Body and Accessories
Entertainment
F5: Module Setup
F0: Radio
F0: VIN Relearn
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I have one but I don't know if it would work because it hasn't been updated for the most recent years, though maybe it doesn't matter. Where are you located? PM me and maybe I can help.
