GM HMI Full Feature Unlock Service

(6 customer reviews)





Our WAMS exclusive custom unlock programming service is now available for ALL 2013+ CUE/Next Gen GM HMI Based Radios! This ship in service for your HMI module allows complete functionality of the radio at all times; no more lockouts when the vehicle changes states. Features are dependant upon what kind of hardware you have for instance if your radio doesn’t already play Bluray/DVD’s when stationary or have Navigation it wont after this programming, but it will allow you to access the other features that get locked out. If you have questions as to which features this will allow you to use please email us. This service is not compatible with non HMI based vehicles such as the IOR/IOS/IOT/IOU family of all in one radios.


All Lockouts removed such as Nav Entry as well as DVD/Bluray and Video Files from USB Storage (e.g. Flash Drives, small solid state hard drives etc)! Access Videos from USB Storage using the Media Button, file resolution should be max resolution of 480 for best results the units do seem to like MP4 formats the best. USB Storage must be formatted in FAT32 format.

Addition of the SMS Texting Application for 2014-2015 HMI to read texts to you while you drive (feature set varies by phone)

Welcome sounds added back in to the unit (with volume control and on/off switch) for some applications.

Adds compatibility for DIVX and AVI video formats for USB Storage.

Adds Backup Camera in Motion for 25 seconds per activation to 2016+ HMI’s This May require plug and play harness to keep the camera on and if so its available from our friends at Harness Dr. You can find it by clicking here! Some vehicles may require a simple wiring modification if a plug and play harness is not available.

Adds Video Playback from USB Storage to 2017+ HMI’s

If you have a 2013-2015.5 vehicle and intend to supply an HMI 2.5 for this service *DO NOT ORDER THIS*. Instead order the proper Android Auto / Car Play upgrade for the required HMI AND Radio with this service as an optional add on under that product. THIS SERVICE DOES NOT ADD CAR PLAY / ANDROID AUTO TO 1.1/2.0 HMI’S NOR DOES IT ADD NAVIGATION TO NON NAV HMI’S!

This is a ship in service for the HMI Blackbox module only. You don’t need to send anything else other than the actual module to us. This service does not include any hardware you must ship in your HMI unit. 

PLEASE NOTE: Certain Application Vehicles will NOT run with the HMI removed, please plan accordingly; you may need a jumper harness which we can assist with. The Map Upgrade is ONLY available for HMI 2.5 Variants.

    WAMS rocks! I have a 2017 Silverado and ended up having to replace my HMI. The WAMS team got my unit programmed and returned cheaper and faster than the dealership!!! They do great work! I had questions so I submitted those via the online form and I was pleased surprised how quickly they got back to me. ~ I definitely recommend these guys!!!

    I am very pleased with WAMS programming service and customer service. My HMI was corrupted and after a few emails WAMS indicated they could resolve my problem. Service was quick and professionally handled. My only issue was that I had to buy a pigtail from another vendor to make my rearview camera in motion work. Great service by WAMS just the same, 5 stars.

    I am extremely pleased with the service and results from my unlock and upgrade. The turn around time was lightning fast. Now my infotainment/navigation does everything I desired and they added a little more. I will use these great people for any other problems I may need solved. I highly recommend their services if your need arises.

    I would like to express how pleased I am with the customer service and workmanship of this company. In this day and age where customer service seems to be a thing of the past this company takes pride in their work and customer service. Any questions I had before ordering their product were answered almost immediately. I sent my HMI in for reprogramming and the turn around time was awesome, the product works flawlessly and just as advertised. Thank you so much to everyone in your company for making this a pleasant experience.

    Great update and quick/easy process. Kids are excited to be able to watch movies on front dash now! Still trying to figure out if streaming from phone via USB cable is now possible though–can you help with that?
