I installed an aftermarket XM radio in my 2008 T4R recently and now have a question. I ran a line from the XM unit (audio out)
to the AUX jack in the console glove box so I didn't have to use FM modulation. Now anytime I use the XM I get a high-pitched sound that is constant anytime the XM is on. If I go back to the stereo everything sounds normal.
Is this some form of interference or something else? Any ideas on how to get rid of the noise?
Thanks....
