Query: No good for 2007 Infiniti M35

Ordered this product after speaking with PAC technical assistance and receiving assurances that this would work in my 2007 Infiniti M35. Well it took a $50 charge from Best Buy's installation team to learn that this information is not accurate. It does not work in the 2007. I will be returning to Amazon.
