Hello Everyone,
I was hoping I could find some help with an audio issue I'm experiencing with my car and the AUX input I (attempted to) set up.
The car in question is a 2006 Volvo XC90, and as I understand it (I'm an electronics novice) the FM signal is converted to a digital signal by the FM tuner so traditional antenna adapters are useless with this setup. There are instructions that were created by a Volvo enthusiast to add an aux input by soldering the two channels on to the positive ends of two capacitors. I attempted to add the aux line and initially had no problems. The following day I went to use the aux line with my XM radio, which needs a power source to run, and I got a high pitched squeal, which I was expecting with something drawing power at the same time as using the audio. Later that day I installed a ground loop isolator to eliminate the noise and my left channel (driver's side) was completely gone! The high pitch noise is gone but I only receive sound out of the right side of the car. Like I said, I have a limited knowledge of circuits, I have a basic understanding of the components and I'm not afraid to do some soldering, but I'm stumped here. Could it be I damaged the capacitor when soldering the left channel? Or is it something more complicated. Below is the link for the write-up for adding the aux and a few pictures of the FM tuner. I would appreciate any help with this I can get. Thanks!
