Chevrolet IOS (Non-Nav) to IOU (Nav) Factory Upgrade

Awesome product, easy to install. It literally took 15 minutes. Also nice to have OBDGenie in the glovebox, if dealer ever reinitializes to factory default settings.

GM Navigation Upgrade

So far- so good! I was looking to add navigation to my 2020 Silverado and that installed easily and appears to be working well. I did not see an upgrade to HD radio, but I am really not too concerned about that. Overall, I would highly recommend this product.
