On my commute to work today, I turned off a podcast and turned on the FM radio and flipped around a bit. I got to a station I haven't listened to in a while and noted how good it sounded, not just sorta better, but like the switch from crap to awesome was flipped. When I arrived at work, I had to email the broadcast engineer to find out what they changed on the audio processor.
The response: "I haven't touched that thing in 6 years."
Well, on my commute home I flipped around to a bunch of stations I listen to on a regular basis and noticed that the bass was a lot more crisp and the treble was more pronounced on all my stations. I had noticed that previously stations were a bit muddy and I figured it was probably an issue with the de-emphasis in the radio, like it was set for the European/Asian standard of 50µs instead of the North American standard of 75µs.
So, I called Nissan and learned that XM will send down necessary radio software updates including those related to Bluetooth and radio performance. They weren't aware of anything recently and suggested that I ask XM, however I'm not an XM customer so I couldn't get any info.
Here's the version numbers from my System Diagnostic screen, hopefully something will jump out at us:
