Frequently Asked Questions - GMOS-01 Metra
Will the Metra GMOS-01 work with my 2005 Chevy Silverado?
Yes, the GMOS-01 is compatible with many GM vehicles from 1998-2013, including the 2005 Silverado. It retains OnStar, factory chimes, and RAP.
Do I need to bypass the factory amp?
No, the GMOS-01 interfaces with the factory amplifier, so you can keep it and retain sound quality.
Can I use steering wheel controls with this kit?
The GMOS-01 itself does not retain steering wheel controls. You will need a separate interface (e.g., ASWC-1) for that.
Does the GMOS-01 work with double-DIN radios?
Yes, it is designed for both single-DIN and double-DIN aftermarket radios.
Will the OnStar still work after installation?
Yes, the GMOS-01 is specifically designed to retain all OnStar functions, including hands-free calling and turn-by-turn navigation.
What is the red wire for on the harness?
The red wire is the ignition 12V input. Connect it to a switched 12V source, typically the red wire from the aftermarket radio.
Do I need to program the GMOS-01?
No, the module is plug-and-play. Some vehicles may require setting the DIP switches according to the vehicle type; refer to the manual.
Will it retain the door chime?
Yes, the GMOS-01 preserves factory chimes like door ajar and key-in-ignition.
Can I install it myself?
Yes, if you have basic wiring and dash disassembly skills. However, for complex installations, professional help is recommended.
What if my vehicle is not listed in the manual?
Check Metra's website for compatibility using your exact VIN or contact their support for assistance.
