Passthru pro IV works great for me. I have been able to program without any real issues( aside from the initial set up and learning curve) Ford GM Toyota HONDA NISSAN

I also have dealer software for Mercedes Benz Xentry/DAS and VW/Audi/Porsche and allows me to use the this device as a legitimate scanner. Love the product!
