radio noise

[wongs83]

Just bought my 07 Metalic Blue Tahoe and brand new to the forum. I've been reading the various post and getting some answers I had, but couldn't find anything on this. When I get in the vehicle in the morning the radio/navigation is making a noise similar to when your computer is working or if it's searching for a CD. The sound isn't coming from the speakers just the radio/navigation itself. Is this common and what is it?

Thanks

I have read about that happening here also. A few guys have mentioned the same thing. I have never had the experience myself though.

Its the Nav DVD spinning up so it doesn't take as long when you go to use it. Kind of like booting up your computer when it sees you coming.

The nav system pre-loads the data for your last known location and caches it so it can display a map as soon as you turn it on. I think it's pretty smart, but it's a little weird to hear that faint whirring / seeking sound that when you open the door or use the key fob... You'll get used to it, and won't notice it any more in no time.

Some customers may comment that there is unusual or unwanted noise coming from the navigation radio. This noise has been described as a fan sound or hearing a disc spinning.

Source of fan sound -- It is normal for the radio fan to run when the vehicle is turned on and for up to three minutes after the vehicle has been turned off and the driver's door has been opened or closed.

Disc spinning sound -- This is a normal operational sound. This is caused by the map disc spinning behind the tilt screen. It is a normal operation after the RKE is used to unlock the vehicle or when the driver's door has been opened. This noise will also be heard during vehicle operation and up to three minutes after the vehicle has been turned off and driver's door has been opened and closed.

Do not replace the radio as the described conditions are normal operating characteristics.



GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
