You can't install a aftermarket radio, the anti- theft system is built into the OEM radio itself. If you bypass the wiring harness then its possible to Burnout you ECM ( main computer) there is a way but it has to be done by a person that knows and understands how to bypass the sercuity system.

I had to rewire the whole car to install the aftermarket radio than the battery light the security light and air bag light was lit went to get it check out now it dont start
