GM OnStar Headunit Replacement for GMLAN Vehicles without Bose
The GMAHLAN is a plug and play interface that allows replacement of a General Motors GMLAN factory radio. It will maintain operation of the OnStar system. The GMAHLAN has on board switching and audio amplifiers which allow audio from the OnStar system to play through the two front factory speakers when OnStar is active. This interface retains all warning chimes, the audible turn signal indicators, rear seat radio control buttons (when optional PESWI interface is used) and the Vehicle Rear Parking Assist System (if equipped).

• Maintains operation of OnStar
• Mutes Radio When OnStar is Active
• OnStar Audio Plays through Front Factory Speakers
• Data Controlled RAP Accessory Output
• Retains Vehicle Warning Chimes
• For additional vehicle integration, use Peripherals line of PESWI steering wheel controls (SWC) interfaces to retain SWCs with the aftermarket radio.  Steering wheel radio controls can be retained to control the new radio by using the PESWI - AKJC, PS, ECL or X.
• OnStar active LED and Ignition on LED.
• Provides +12v switched accessory output. No more searching for switched +12v in fuse box or kick panel.
• New radio will operate with the vehicle RAP (Retained Accessory Power) circuit. The radio stays on after the key is turned off and stays onfor approximately 10 minutes or until the drivers door is opened.
• The GMAHLAN does not retain the factory XM receiver. You will lose the XM option when the factory radio is replaced with an aftermarket radio.
• If you are not retaining the OnStar system, use the GMCOL29 instead of this GMAHLAN interface.
• Built in Smart Mute Circuitry will play OnStar audio through the front speakers while muting the radio or turning the radio off if a mute input circuit is not present
