My second Denali hack/tweak... COMPLETE RADIO UNLOCK!

[GTPprix]

Just to confirm. USB still works in the back while moving.

Is this proprietary software you used for this?

Not sure about the back, the way its setup I don't think so. You CAN do USB at the front and DVD/BD at the back I tested that.

I own a company that develops custom software for GM vehicles.

What video formats does it read, I can't figure mine out.

And how much for the unlock??

 

[GTPprix]

It's not going to do much without the unlock It's $199.

What do you need to do it and what kind of issues have you had. Worried about dealer support.

Remove the HIM (Human interface module) i think that's what it's called, From the truck and send it to GTP he modifies it then sends it back to you.

However I am curious to know what this does for dealer support?

Nothing. It's software, they cant even tell its there.

PS its actually the Human Machine Interface Module or HMI.

What happens if there is an update released to the radio...i.e. to add apps or something else...if the dealer reprograms do we lose your unlock and if so do we have to pay 199 over again?

 

[GTPprix]

A normal update wouldn't overwrite this but if it somehow happened a copy of the repair order would get you out of any payment
