8.4" to 12.1" screen replacement

[busa2009]

Sorry for the late reply. I initially blew the 15 amp fuse when repining the blue plug. Windshield wipers wouldn't turn off and got a bunch of errors. Replaced the fuse, but screen wouldn't turn on. I then checked every fuse in the cabin and under the hood but all were good. No radio and no display on the screen.

If your screen isn’t turning on then your alpha obd steps didn’t take. Go recheck
Also unplug battery or unplug radio fuse for about 3-5 minutes

Just completed my 8.4 non nav to 12" nav upgrade. Thank you @Jimmy07 for your help and Kodatech. Radio was sourced from eBay and had never been installed in a vehicle. It took more time to unplug the harness's than anything else!

The only features not working are the heated/cooled seats and steering wheel heat. When I access them in the menu the icons are greyed out! Is this something that will correct itself after a few cycles?

Update, all functions are working now. Heat and cool seats as well as heated steering wheel

Typically it should return in a few hours. Whenever I disconnect my battery for extended time it takes a few hours for my options to show up such as sirius, backup cam, heater seats, etc...

Does anyone have a complete list of parts needed?

You need a display, bezel, module, LVDS cable, and a way to program your BCM like AlfaOBD

The radio is not nav! I'm hanging on to it until in certain there's no issues with the 12" upgrade

I was able to get through the swap in an evening. For the HD guys, I'd highly recommend the kaodtech bypass as it allows you to not have to get behind the gauge cluster to do the bypass.

Pry the red face off of the connector. Then insert a paper clip in the front underneath the terminal to pry up the plastic terminal lock. You’ll push in on the wire while prying up the plastic locking tab, then pull on the wire once the tab has cleared the terminal.

What about if your screen comes on but then prompts a four digit pin???

 

[PorBoy]

^^^^. Where did your screen come from ?

Then you’ll need to obtain the anti theft code from whoever you bought the radio module from, or the dealer. You will need the serial number off the radio module and the VIN from the original donor truck to get it from the dealer. Or, you can pay to get it from this site- https://www.ivgsoft.com/
Make sure to get the serial number and model number off the radio module before you install it.

The screen and module came from a totaled truck here in Houston... I doubt the owner has access to the truck now

If you don’t know the VIN of that truck, you’ll have to use the link I provided to get the code.

Pull the radio module and post the serial number on the radio. It is on a white label usually begins with T. Maybe others. Number sometimes by bar code also. Take a picture of the labels and post them if not sure. Or send me private mail.
