I’m in a similar boat. Best Buy wouldn’t install on my car cause it’s a manual, even though it has a neural safety switch. Being an ASE certified mechanic and mechanical engineer, I decided I’d just do it myself. Found out after the fact that it needs to be programmed by an authorized dealer. Best Buy refused. I’m now stuck with a $400 remote start installed in my car that doesn’t do anything. Did you ever get your issue worked out? If so, how? I wish they’d just give me an account for a few days to program it and then they can close it. ?
