ClassC5

I gave up on this issue about a year ago because my forehead hurt from banging on the wall. I've decided that since the XM works so well that GM must be getting some rebates from them and could care less about the FM issue! A new issue is that when playing music (via Aux & bluetooth), from my iPhone, 90% of the sound comes from the left front speaker. Doesn't seem to matter what settings I change on the stereo system or the phone. I haven't tried it with a cable. Has anyone else had this issue?

I'm new to this blog. Who is Jennifer and how do I contact her? You can add me to the list of "lousy FM reception". My 2014 GMC Sierra SLT has less than 500 miles on it and I've already had it to the dealer. They either lack troubleshooting skills or there are no diagnostics for the new system. Thanks!

The FM in my 2014 Sierra SLT faded in & out on the way home from the dealer! Worst FM reception of any vehicle I've driven in the last 20 years. Nearly $50k for a 'high tech' pickup and the radio sucks. As with many other posts, the XM works great, I don't know about AM, but FM is useless. Other than that what a great rig… otherwise very impressed so far but just hit 500 miles. I've had it to the dealer about this but what surprises me is they either don't know how or are unable to run basic diagnostics. I will be reporting to GMC to see if a fix is in the works. I am vary disappointed with this.
