I started a thread a couple of months ago but now that I know details of my problem I'd like to start a fresh thread.
I have a 2019 non-nav Limited. Good sound is really important to me, so I decided against buying a factory audio upgrade and having a custom audio system installed. Details of the install are here
. The install consists of an external 6-channel power amp (125 watts per channel) connected to the stock head unit, and six new speakers replacing the stock speakers.
Some time after the installation was done the red error light on the overhead Starlink console came on. I got an email warning saying the STARLINK emergency services in my car may be inoperable. The STARLINK Emergency Services such as Automatic Crash Notification, SOS call, Stolen Vehicle Locator and Enhanced Roadside Assistance—may not be available. Since these functions deal primarily with your safety, security and remote services, it's important you stay connected. Please contact your Subaru Retailer right away.
I checked some of these services, which work fine: calling SOS (red button) and Info (blue button), as well as Vehicle Locator from my computer. Other stuff I'm not sure.
Eventually I took the car in to service. They checked the problem, it has to do with Telematics, and I took a picture of the three error codes that appeared - see photo. 1. Left Speaker/Audio Circuit 2. Right Speaker/Audio Circuit 3. Mute Line Circuit. They cleared the codes, and the red error light went away. But a few days later the red error light returned, along with the same email warning. The service department said the amp was changing the voltage level of the audio connections, causing the error. The car's electronics are very complex and can't be altered like this. The bad news is he told me my warranty could be voided because of this.
Before I go back to the audio shop, I was hoping to get some advice here. Could the installer have done something wrong to cause the error? My hunch is that the installation is not messed up, and the amp is creating the problem, like the service guy said. But shouldn't the car be able to handle an amp install like this without causing problems? I appreciate any advice.
