Hello everyone,

I purchased my car a few months ago, and I though I got the premium pakage on my car which includes the upgraded power on my sound system, I didn't get the NAV with laguatronic. If I wanted these upgrades what steps would I need to follow as a DIY project?

I tried searching the forum but after an hour gave up, so if there is a thread please direct me with a link.

I hope the answer isn't going back to the dealership.
