Mylink / Speaker Issues

[Calorim]

I bought a 2014 Sonic RS with 15.8K miles on it about 3 weeks ago. I didn't notice it when I bought the car, probably because I was excited. However, when I turn on the car the front left and right speakers do not play the radio, or any sounds (chimes, turn signals). But after anywhere from 30 seconds to 5 minutes both front speakers work. When they don't work I hear a bunch of static in the front.

Second issue: the drivers side rear speaker does not ever emit any sound.

The car has a build date of 07/14. Also, please see the attached pic of the MyLink HW and SW numbers.

Does anyone have any idea if this is a firmware thing or a hardware thing?

Wonder if all connections are working?... but the delay seems software...

Still under warranty, so that's a plus....

Yes that is a plus. I scheduled an appointment, but 2 weeks out is the first I could get in. Maybe a dumb question, but since I bought it used, does the warranty cover the car 3 years or 36k miles regardless of who owns it?

it should if its a dealer warranty from when the car was purchased new. the only way it could bite u in the ass is if the previous owner put in an aftermarket system and completely butchered the stock system when they returned it to the dealer. that would void the warranty work on the entertainment system

From a quick look around it does not seem to have any altered wiring or anything like that. I have an appointment setup for this Saturday for the dealership to take a look at it.

Also, I found out that the USB playing of MP3 is also not working. It played the USB 1 time be now every time I start the car it does not play or even recognize that I have a USB plugged in. So I will be letting them know to look at that as well. It is sounding to me that it is either a faulty head unit or need a firmware update to correct these issues. I will post how it goes once I hear what the dealer has to say.

i tried a cheap ****ty usb the first time and it didnt work like u said . went to staples and bought a new staples brand usb and has worked fine ever since.i wonder if ur car has ever been struck by lightning?

Just pull the head unit and have a look around to see if it looks like someone did a quick and dirty reinstall of the factory unit.

PS Did you do that with the emblems?

 

[Calorim]

I dropped it off at the shop today. They have been working on it all day. They gave me a rental because they are trying to track down what is going on.

The emblems were like that when I bought it. I assume they are standard on the 2014 RS at least.

The badges are not standard. The previous owner installed them.

GM speakers are know to fail from water infiltration. If you car sits outside all of the time or you live in a very rainy area.

I recommend installing Polk dB speakers. 6.5 in the front and 6.5s in the rear. They are very efficient and mate well with the OEM amplifier output. They are also marine certified. You can find them on Amazon for very reasonable price. I would also recommend adapter plates and speaker wiring adapter kits. When installing, please make sure you use the provided foam isolation ring that comes from Polks; and remove and transfer the narrow foam tape from the GM speaker housing and place on the new adapter plates. If you need additional info, please don't hesitate to send me a PM or look me up on FB.
