How to Bypass Onstar for Aftermarket Radio

OnStar is a subscription-based service that provides safety, security and remote diagnostics for your vehicle. If you cancel your OnStar subscription, you will no longer be able to use the OnStar system. However, you can bypass the OnStar system by installing an aftermarket radio in your vehicle.

  • Find the OnStar fuse in the fuse box
  • This is usually located in the glove compartment, although it may be elsewhere in your car, depending on the make and model
  • Remove the OnStar fuse and replace it with a new one of the same amperage
  • This will disable OnStar’s ability to communicate with your car
  • Connect your aftermarket radio to its power source and turn it on
  • You should now be able to use your aftermarket radio without any interference from OnStar

Stereo Wiring Harness

If you’re looking to upgrade your car stereo, a new stereo wiring harness is a great place to start. This article will give you a detailed overview of stereo wiring harnesses and what they can do for your car audio system. A stereo wiring harness is an aftermarket product that allows you to connect your new car stereo to your vehicle’s existing factory wiring.

These harnesses come in two main varieties: butt connectors and T-connectors. Butt connectors are the simplest and most common type of harness, and they simply plug into the back of your head unit. T-connectors, on the other hand, split into two halves so that one half can be connected to your head unit while the other half plugs directly into your vehicle’s factory connector.

While both types of harnesses will get the job done, we prefer T-connectors since they provide a more secure connection and are less likely to come loose over time. However, if you’re working with a tight budget, butt connectors may be the way to go. Once you’ve selected the right type of connector for your needs, it’s time to wire up your new car stereo!

The first step is to identify all of the wires coming out of your head unit. There should be four main groups: power (typically red), ground (usually black or brown), left front speaker (green), and right front speaker (purple). If you’re also installing a subwoofer, there will likely be an extra set of wires for this as well (typically green/purple for left/right).

Next, match up these wires with their corresponding counterparts in your vehicle’s factory connector. Once everything is plugged in, turn on yourhead unitand test outyour new speakers! If everything sounds good, then you’re all set!
