Frequently Asked Questions (FAQ):

Where can I purchase a wiring harness to install an aftermarket stereo?

Any local audio retailer should have a harness, mine came from Best Buy.

I do not have a code for my stock radio, where can I get one?

The dealer should be able to supply you with this code as long as you have a serial number for the radio. If not the dealer, then there are various sources online who provide this service as well.

My radio went into lock down mode, what can I do now?

You can only enter the code in a maximum of four times. If each of those times was incorrect, then the stereo will need to be left on in the radio position for an hour until it will reset. Then you can continue to enter in the correct code.

My radio will not turn on, what is the issue?

First check the main fuse panel in the car, then continue to remove the radio and check the fuse in the rear of the radio. If that is not the problem, then use a multimeter determine if there is power present at the vehicle's harness. If there is not, then there is a vehicle wiring issue. If there is, then the radio is faulty.
