Frequently Asked Questions - AXM50-GM1 Metra
Which GM vehicles is the Metra AXM50-GM1 compatible with?
The AXM50-GM1 is designed for select GM models from the 1990s to early 2000s, including Chevrolet, GMC, Buick, and Oldsmobile. Check the vehicle compatibility guide on Metra's website for exact models.
Does the AXM50-GM1 require any special tools for installation?
Installation typically requires basic hand tools like a screwdriver, wire strippers, and crimping pliers. No specialized equipment is needed.
Can I use this kit with a double-DIN aftermarket radio?
Yes, the AXM50-GM1 supports both single-DIN and double-DIN radios. However, some double-DIN units may require an additional installation bracket for a secure fit.
Does the harness retain steering wheel controls?
No, the AXM50-GM1 is a basic wiring harness and does not include steering wheel control retention. For that feature, you would need an additional adapter (e.g., Metra ASWC-1).
Is the AXM50-GM1 plug-and-play?
For many GM vehicles, yes—it connects directly to the factory wiring harness. However, some models may require minor wire splicing for illumination or accessory power.
What is the antenna adapter included?
The kit includes a standard Motorola-to-GM antenna adapter, allowing you to connect an aftermarket radio antenna to the factory GM antenna plug.
Can I use the AXM50-GM1 in a vehicle with factory amplified audio?
The AXM50-GM1 is designed for non-amplified systems. If your vehicle has a factory amplifier, you may need a separate amplifier bypass harness (e.g., Metra 70-1858).
How do I identify the correct wire connections?
The harness follows the standard aftermarket color code (e.g., red for ignition, yellow for battery, black for ground). A wiring diagram is included in the instructions.
What should I do if the radio doesn't power on after installation?
First, check the fuses in both the vehicle and the radio. Then verify that the yellow (constant 12V) and red (switched 12V) wires are properly connected and have voltage.
Is the AXM50-GM1 compatible with OnStar or other factory systems?
The AXM50-GM1 does not interface with OnStar, chimes, or other data systems. It only provides basic power and speaker connections. Retaining those functions requires additional modules.
