XM low volume fixed!

I discovered this, you can customize the the eq and sound for the entire fm band with one setting, but you must save each XM preset's setting individually on my Nav radio.

I think XM uses different bit rates for different stations. I recall they use a low bitrate for talk stations. They may be upping the bit rate on some stations yielding batter sound.
