2013+ GM HMI Full Feature Unlock (For Existing AutoSync Customers)




Our WAMS exclusive¬†custom unlock programming service is now available via AutoSync for your HMI 2.5 equipped vehicle! This optional programming for your HMI 2.5 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 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 IOB/IOR/IOS/IOT/IOU family of all in one radios.
