Radio not working

Hello:

I have a 2003 Infiniti i35 with the Nav package. The Bose radio is different with the Nav package, since the 10 CD player is in the trunk, with a single CD player in the dash, for radio or Nav. The model printed on the front of the radio is CK130.

The problem is, apparently at lower temps (below 40 deg), the radio fused circuit has a load of over 2 amps, with nothing on - radio OFF, Ignition Key OFF and removed, car left empty, locked or unlocked. This was discovered when the car would not start due to a dead battery - even though it was fine and just replaced a week ago! I checked with a current meter and troubleshot it down to the 10A radio fuse under the hood. Fuse removed and battery recharged - absolutely no problems starting in cold winter conditions, but no radio!

Also, note the following. Before this occurred, the radio exhibited bizarre behavior in our garage at colder temperatures, starting this fall. I would walk out into the garage too find the Radio ON and producing music, when the car was turned off, key removed hours ago, but only when the radio is left in the ON position. When the radio is left OFF, the same current drain (minus ½ amp) exists without evidence of it being on. Yikes! This obviously makes me suspect the radio itself.

Now with the fuse out, I realize the Nav system no longer works either. So the current drain could be related to radio, Amp, Sub Amp, or Nav system.

My inclination is to remove the radio, test it at 30 deg for a current loss and then if it is OK, the other components in this circuit.

But how do I remove the radio? I have conflicting procedures, believing they are related to the non-Nav Radio package. One repair procedure mentioned a Plastic Trim Removal tool as if it was a common household item! Help!

Thanks so much,

Hi Docfixit:

Yes, the fuse is in the fuse box under the hood, left hand side. It is a 10 amp, blue, double spade type. What did you mean by "#30"? Can I get the trim tool at Pep Boys? Is that the whole name? Is it specifically for Infiniti ?

If your car is like mine the smaller amp to the subwoofer stays on. The bigger amp visible underneath trunk is pushing mids and highs but the smaller one I believe is under the sub. Try unplugging the connector. That might fix your problem. Radio might sound like sht but you'll have sound and GPS.

Hope you found a fix but if not maybe this will work.

Radio will not turn on. Fuses are good. Disconnected and reconnected the battery, still nothing. Is there any other reset procedure for this car?? I can only control my stereo through the steering wheel controls. I recently had my battery die and replaced. Is there anything else I can do to verify it went into theft lock?

Is there a flashing light or a lock on the LCD? It sounds like the radio got a voltage spike causing the voltage converter to go out.

No there is not, the screen is blank, but the stereo makes a loud beep on car start. I've checked the fuses and reset the stereo by disconnecting the power for 15 minutes, it will eject the cassette, at which point I can put a new one in and it will play that, but otherwise all controls are locked on the actual stereo/CD Player/Cassette.

It sounds like the radio is no good but to be sure lets test the power and grounds to make sure the wiring is okay.

Here is a guide and the radio wiring diagrams so you can confirm the failure.

Please let us know what happens.
