Removing the HMI Module

[whoseanthony]

Ok sooooo in the over excitement of taking out my HMI module and getting the hack done I did the cut/splice method above. Unfortunately I forgot one key step. Mark which white and which blue wire go with what. Since these are the same color is there any other identifier as to which is which for when I reconnect everything? Or (what I am hoping) is that it doesn't matter which white and which blue connects as it is just meant to close each respective circuit. Any and all her/advice would be appreciated.

So it seems the wires do just complete the circuit. Soldered everything back together and blues-blues and whites-whites and the truck and system are working perfectly. Great hack!. Next up AppleTV for in Car Airplay

I need some guidance here. Am I suppose pull anything out of this box or do I just ship the whole thing? No need to jump anything here, I can let the truck sit ideal until it comes back. Thanks

Just that box

I'm bumping a heck of old thread, but...

Any shops in the Bay Area of California that are familiar with this? I want to unlock the nav and the movie screen on my new Denali xl... However...I just had a pretty major surgery and am not physically capable of getting in and out of the car to do this mod, and probably won't be for a couple more months...

The wife is 3-4 weeks of delivering our first, so I am sure there is going to be lots of long trips to her families house 3 hours away...

Can anyone recommend an install place? I'd be happy to do the core exchange so it could be an in and out experience!

Thanks

I'm sure gm-navigation.com could direct you to an installer in that area for that product

Does anyone know the part number of the HMI J1 connector?
